- In the 18 elements of the 5th period, the sublevels fill similar to the 4th period(see previous blog)
succesive electrons are added first to the 5s sublevel, then the 4d, and finally the 4p.
-if you look at the periodic table, it flows straight across. A video from my comment last Friday explains this.
- Sample Problem B: (a) Write the complete electron configuration and noble gas notation of the semi-cool element. aka-iron (Fe); atomic #= 26 [not as cool as Rubidium, which is in problem C]
- (b) How many electron-containing orbitals are in the semi-cool element iron? How many orbitals are completely filled? How many unpaired electrons are in one atom of iron? What sublevel are the unpaired electrons in?
ANSWERS: (a) [1s2,2s2,2p6,]->10[3s2,3p6,4s2]->10[3d6]-- the 10s are Dr. B's way of grouping electrons so you can keep track of them (they do like to move around a lot)
(b) electron containing orbitals-15 (REMEMBER--s=1 orbital;p=3 orbitals;d=5; and f=7) count them up for each level/ completely filled orbitals-11(you can see this by drawing out the orbital notation aka the arrow-line things)/number of unpaired electrons-4 (all those lonely arrows)/the orbital of the unpaired elecrons-3d (where the lonely electrons are found)
- For more practice with this stuff, check out sample problem C in our book.
- HOMEWORK-#11 P. 125-126 #33-41 AND study for that test on thursday, sounds like a doozy
test help Ch. 3 -p. 88 and 89 in our books
Ch. 4 - p. 123 Dr. B told us to know all the vocab and ideas from the chapter.
If you need help, e-mail Dr. B, search your friendly internet, or just pray to Our Lady of Partial Credit on Thursday
P.S. This blog is in honor of the great Griff "doesn't have a nickname that I know yet" Moran.
Here are a few quick problems with explanations.

ReplyDeleteThis site explains electron energy levels and provides another memory device for the filling order.
This is a website that gives many example problems for you to do.

A worksheet on orbital notation
ReplyDeleteteacherweb.ftl.pinecrest.edu/piersog/.../WS-Orbital%20Notation.doc
Why is the noble gas electron configuration for Lr (Lawrencium) [Nr]5f^14 6d^1 7s^1? Why is it not [Nr] 5f^14 6d^3? the 6d is not filled yet it goes on to the 7s?
ReplyDeletesomething for the quiz tomorrow, go over the vocab in the chapter and know the difference between the three classifications of the elements. the last quiz was not just problems and i would bet money that this one would be the same.
ReplyDeletep.s. thanks for the extra credit on the blogs Dr. B
p.s. everyone take a look at will brantley's post it has a basic guide on some key points to study
ReplyDeletehere's an overview of electron configuration and quantum numbers.

I am pretty sure that the orbitals fill 4p then 5s then 4d, not 5s then 4p then 4d
