Good night everyone.  
 
Just one last thing, we are doing the long answer question, like calculating energy and wavelength and such?  tomorrow is only over the multiple choice section.  You need to retake the other sections after or before school.  -- or lunch
 
ok sounds good,
 
Okay, thank you for your time! Good Night! 
 
I am nearing the time when I need to sign off.    Do you have other pressing issues?
 
 
 
was the answer to #31 E? I had C  E.  There would be 4 upaired in the iron ion
 
Will you please explain 35? I have B but I don't remember how I got it. 
 
The most easily removed electron is the one on the  outside.  It will have the highest value of n.  In number 35, you are sked about K, so its highest n value is electron in 4s1.  This will be the easiest one to remove.   
 
I have a periodic table with a few basic quantum nuber notes on the back, will I be able to '
use this on the test? also is this question answer thing still happening? Im confused. 
Could we go over tge answers to a few questions about periodicity Oh, I'm sorry...  
 
which question?    Question wait...... 7  is that the one about adding an electron to He? Yessir
 
Check out this link
 
What is the Beer Law Lab?   it is a lab that we can't do at GCAA because we don't have the right equipment. 
 
Oh, because I was on that online chat and I was so confused.   :  )
 
Since this stuff is not on tomorrow's quiz, I think I will ask you to look over my on-line explanations first, and then ask me about the explanations.  
wait so the retake is over the quiz we took last wednesday and i wasn't here that day. And I don't have my quiz.  I gave the tests back last Wednesday.  did you get a copy of the multiple choice? What multiple choice? The one you gave back on.. .Tuesday?
 
Send me an email and I will send you a copy of the test.  michael.howe@grandcenterartsacademy.org Alright
I sent the email  I am waiting for it to come through.....may be hung up in security.... send to mphowe@yahoo.com 
 
Did you send again?  I got it on the yahoo account.  The attachment is a word document.  Can you handle Word?
 
 
What were the answersand then there are 3 orbitals in the p sublevel to 16 and 17 I will check...the 5th energy level would have 5 sublevels(spdfg)  A p sublevel has 3 orbitals.
-1, 0, 1 yes
Oh, now I get 17!   :  )
I will give you a new table.   And yes...I am still here answering questions Mirabai.....
Ok cool.. but I wont be able to use the chart I have on quantum numbers?  you need to know it.  
 
does it look like this?
 
n        l        m        s
4        0        0      +1/2 or -1/2
        1        -1,0,1   3 (+1/2 or -1/2)
        2    -2,-1,0,1,2    5(+1/2 or -1/2)
        3 -3,-2,-1,0,1,2,3  7(+1/2 or -1/2)
 yeah  
 
 so...n can be from 1 to infinity.  l can be from - to n-1   m can be from -1 to +1 and s can be +1/2 or -1/2
 
 l = 0 is called s.......l = 1 is called p   l = 2 is called d and l = 3 is called f
 
 Yeah I understand it I dont have it memorized exactly though and I just wanted to know if I could use it on the test. Thanks ok   you're welcome   :  )
 
Hey so, #19: How many values of the quantum number m are in the f sublevel I said 3 and it wasn marked wrong, why was it wrong?   If l = 3, then m could be -3,-2,-1,0,1, 2, 3
here in the main window.....Caecilus-- are you here?  could you review what all the sublevels mean?  I am not sure I understand your question.  Energy levls are divided into sublevels, sublevels are divided into orbitals.  s sublevels are spherical, p sublevels are shaped like dumbbells, and d sublevels are double dumbells, or a dumbbell in a donut.
Where can we find the animation of this  on your site  The ORBITRON has pictures of orbitals.  I will look for an alternative real quick.....
Woah woah where doing the animations on this test as well?
try this.  I showed it in class one day....http://www.youtube.com/watch?v=K-jNgq16jEY
 
Random----there will be no harder questions than were on the first test.
 
Oh, sorry. Yes I am here.  Okay! I also am still confused about the factors for decreasing and increasing within the series and the families.   This is not on tomorrow's test....but here is a quick overview.
 
in a series, as you move from left to right, you are adding protons without adding energy levels.  This causes size to decrease.  Size decreases because more protons pull harder on the electrons.  This causes an increase in the amount of energy needed to remove an electron (ionization energy) and also increases the atoms attraction for electrons.  (electronegativity and electron affinity)
 
within a family, the addition of protons is cancelled by the addition of energy levels, so size increases from top to bottom.  this lowers ionization energy and also lowers the atom's attraction for electrons
can you review the shielding effect once again..not on tomorrow's test.  but shielding effect simply means the inside electrons are pushing the outer shell away from the effect of the nucleus.  
 
So what are some things that are on the test?  The same type of questions that were on the 40 question atom test that we went over last Wednesday.
 
that you should have in front of you now....  :  )
 
Will the same people be on the test?
yes
Inert gases don't react because they have full s and p sublevels.  This means that they would not move to a lower energy state by gaining or by losing electrons....so they don't react.
 
hm.....How........ do you find the equality or inequality of protons in an elements?  I am not sure what you mean.  Did you mean to say electrons?  --as in the isoelectronic question?
 
How many electrons are in a F- ion?  Answer:...... lemme pull out my chart.... 9?There would be 9 in an atom, but in the negative one ion there would not be 9.  how many would there be?    Answer.....?   ....    10? because + is subtracting one?
yes.  Now.....how many electrons are in an atom of Ne?   Answer?....
yes yes... I don't know how to speak today...   Um..  10  yes.  So would'nt that mean that a negative one ion of Fluorine and an atom of Neon are isoelectronic?   :  )
 
 
YES!!! I GET IT NOW!!! ^__^
Are you guys still there?  Did I miss a question?
Im still kinda confused on how to find s in quantum numbers
 
the first electron in each orbital gets assigned a value of +1/2.  The second in would be assigned -1/2.  So, if you had three orbitals for example, you would assign as +1/2 +1/2 +1/2 then  -1/2.  -1/2.  -1/2. Alright so IN for example would have a s value of +1/2? yes.  but the s value is not for "In", it is for the last electron in the filling order of In.
and the last orbital in Xe would be -1/2 correct? yes
I dont think so...
 
Can you give a quick overview on how exactly to find the quantum numbers of an element ?
 
they are for an electron in an element.  Pick an element and we will do the quantum numbers for its highest energy electron.
Argon! What do you mean by highest electron? Sweet.  the last one in the filling order.  for Ar, it is the 6th electron in the 3p.
fill in the blanks....
  n =    waiting.... n =3?  good.  l = waiting again   l =  ?    1 was correct.    M would equal 1 and s would equal -1/2  1 is the third orbital and -1/2 is for the second electron to enter the orbital.
  Oookay... I belive I understand... Will review notes... 
  What if the element is +Ar or something? ( does that mess with the quantum number?  only in the sense that the quantum numbers would describe the electron in its new position. for example if you had Ar+, the numbers would be n = 1, l = 1, m = 0 and s = -1/2.   You would now be describing electron number 5 in the p sublevel. 
  
  If N=3 then L must equal.. 2?  0 or 1 or 2.   But in the case of the las electron in Ar, l would equal 1 since the last electron is in the 3p sublevel
  0 s
  1p
  2d 
  3f  yes
On number 40 I don't understand how to get the answer i know what h and c are but not how to divide correctly to get the answer, please
 
E = h √  so just multiply h by frequency.  Also....use the ee or exp key on your calculator.  Do not use the x10 or ^ buttons. Okay I get it now thank you 
 
Explain the electron filling order real quick please.  :  )
^Please
ok whatever, Im just thowin this stuff out.
Let me find a link.......
Oh.... so its basically the order atwhich the sublevels go?  yes Good to know
Right got it cool, just a little confuzed on the phrase
 
this one is pretty good (my color changed)  Remember that 4f follows 6s
 
How do I solve #35, the one asking about the most easily removed from the ground state  The most easily removed electron is the one on the  outside.  It will have the highest value of n.  In number 35, you are sked about K, so its highest n value is electron in 4s1.  This will be the easiest one to remove.   
 
for every time there is a question with "how many electrons in -- have a +1/2s value" do we just divide the protons by 2?
 
electrons in an atom are equal to the protons if there is not a charge.  +1/2 spin refers to half of the number of electrons because if the energy level is full, half would spin clockwise (+1/2) and half would spin counterclockwise.  So, yes dividing the protons by 2 will work..  Really though, you are dividing the number of electrons by 2.
 
Is helium 1s? 2s?
Helium is a 1s2.  It should be above Be on the periodic table, but it is placed above Ne because chemically, it acts like Neon.
so what were the main problmems we had on the test well, what is the toughest subjects n the test
 
 
Hello Everyone
 
POST QUESTIONS Below.  I will check on them periodically.  Remember----this is a completely public forum.  BE NICE.   :  )
 
10/16    previous discussion questions are below......
 
 
 
What are we going to cover on the test?
 
Atomic structure, PNE, the math that is in the podcasts, electron configuration and quantum numbers.
 
So wavelength and all of that jazz.   Yes---the problems will be like those on the podcasts that I have been telling you to study..... :  )
yes and I am currently viewing them, well nevermind
but...
is this mr howe?
I am blue...yes...at least I am blue on my computer in des peres.  : )   Do you have any questions.....
Hello~ Will we be able to use periodic tables on the test?  yes.  you will always be able to use a periodic table.
Ok~ thank you~
I will give you the formulas and constants.
give me a bit I havnt developed questions yet 
 
How much of the podcast math will be on the test?
  all of it
okey dokeys... and this is going to be a harder test as well...  It won't be hard if you have practiced the on-line quizzes and if you understand the electron configs--and if you understand the practice test.
Im reletivly confuzed because what we have been learning in class hasnt seemed as math heavy as these podcasts seem to be. I understand them though
 
the three places we did them were the light math from about 2-3 weeks ago, the candinium lab conclusions and calculating the wavelength of a duck and electron.  The most difficult one is number 5.
so will derivatives be on the test as well? or what we did like that with wavelengths.  derivatives?   in class when we were learning wavelength, you spoke about deriving
oh...you will not need to derive the formuls.  they will be given...
ok!
since you guys are not inundating me with questions, I am going to take a 15 minute break.  I will check back at 8:35
Excellent sorry it is taking so long im just workin out these problems
yeah, seems like not too many people are here at all...
 
I am back....on a different computer, so it seems that I may be a different color?  Any questions?
what kind of electron config. will be on the test? will it include dot diagrams? 
 
dot diagrams and orbital notations.  for example, how many pairs of electrons are in the outer shell of P?
let me get my table....
 
3?  only 1.  The config ends in 3s2 and 3p3, so the only pair would be in the s sublevel.  The p's would be single due to Hund's rule.  (P = phosphorus)
Oh right right, I was thinking sublevels for some reason, I gotcha though
 
Will you explain Hunds rule again?
yes.. when you are putting electrons into orbitals within a sublevel, the electrons will go in one at a time until each orbital has one electron.  THEN....they begin to pair.  so in a p sublevel you enter the electrons as single, single, single, then pair pair pair.
 
OK i understand all that... I just dont understand how you know how many singles you make until you start making pairsuntil each orbital has one electron
 
well it would be until every one has one electron in it, right? yes once it's filled up, then it starts pairing off. yes
 
what is one? every what gets one?
every positive then negative electron im pretty sure sorry i meant proton or I think???
no, it's just electrons. they go in one at a time, then pair off when there's no more room to be alone. it's just electrons though. not protons. correct
OK I WAS SO CLOSE THOUGH DARN IT
 
 
I have been trying to paste an image, but don't seem to be able to.  
???
so this is for the phosphorus configuration from earlier?  yes.  it also shows Hund's rule, in that the three electrons in the p sublevel are unpaired. 
 
Will we be able to use the chart of s and p and ds and stuff?  you will be able to use a periodic table.  It IS the chart that has the s and p and ds and stuff.  :  )  you will not be given the diagonal rule.  You will need to understand the filling order as the periodic table tells you.  
 
 will we be using our own periodic tables or new ones that you give us
new ones, but I intend to give you one like the one you have.  It has the sublevels marked.
 
Will part of the test be over what was on the matter quiz
no.  just atoms.--like the practice test.
 
will the test show elements as the symbol or the english version.  maybe symbols, but the periodic table has both the symbol and the name. (I think).  If not, you can ask me.
 
What does PNE stand for? protons, neutrons and electrons Well now i look dumb... more like DUM 
(Not an answer to above) thank you for the help!~ You're welcome.
 
Any time zoe! :) lol
 
So explain the equation real quick, its easy just give me the appropiraite terminology
The ml quantum number for an electron in the 5f orbital
 
a 5f orbital has an n value of 5, and an l (L) value of 3.  The ml (m) quantum number could be -3,-2,-1,0,1,2,3'
Is this what you mean?
yeah sweet, thats what I meant, sorry it took me so long to reply.
 
How did you know the L value  L can be from 1 to n-1.  so if n = 5, L can be 0,1,2,3,4.  or s,p,d,f,g    so....f = 3
0,1,2,3,4
 
which equation?
there are three math equations.  they are in the podcasts.  If you need them, I need to go to my laptop for the greek alpha......
 just for recap, breakdown the dot diagram real quick  dot diagrams include only the outer shell electrons.   These will only be s or s and p.
 
 
How much longer will you be on mr howe? just as a time slot   I need to drop off in a few minutes.  I can check back one more time at 9:55.
ok kool
 
 
For the M quantum number to be negative what would have to happen and what would that mean?
The m quantum number can be from -L to +L.  So if L= 2 for example, m would be -2 or -1 or 0 or 1 or 2.   five values.  five orbitals in a d sublevel.
 
My wife just got home, so I need to talk to her.  She has been at the Eastern Regional Figure skating competition.  (her student won the Novice Men division--landed a couple of triple jumps cleanly).   any other quick questions?
 
seeing none........   good night.  :  )
