Quantum number problems I'm unsure of ...

OpenStudy (ams98):

@JFraser

OpenStudy (jfraser):

"3p" tells you two of the 4 quantum numbers, right off the bat.

OpenStudy (ams98):

So these are the ones I got. 3,1,-1,1/2 3,1,0,1/2 3,1,1,1/2 3,1,-1,-1/2 are they right at all?

OpenStudy (jfraser):

all of those are options, and all of them could be correct. If all you need is one valid set of QN's, any of those should be correct

OpenStudy (jfraser):

use the rules, one at a time.

OpenStudy (ams98):

A or D I think D

OpenStudy (ams98):

@JFraser

OpenStudy (jfraser):

it's D, but my question to you is: why? which piece is wrong?

OpenStudy (ams98):

The maximum value assigned to l "azimuthal quantum number" is n-1 ,ie 1 less than what is assigned to principal quantum number, so it makes D wrong. @JFraser

OpenStudy (ams98):

I still have a few left. Next:How many electrons in the same atom can share the quantum number n = 2? and I got 6 is that right????

OpenStudy (aaronq):

nope, n=2, can have l=0 (2 electrons), and l=1, (6 electrons) for a total of 8

OpenStudy (ams98):

Yeah I got it after I posted but thanks so so much!

OpenStudy (aaronq):

good stuff. no problem !

OpenStudy (ams98):

While your here, haha Consider the compound Pb(CO3)2 and answer the following questions. What is the name of this compound? What is the molar mass of this compound? Explain how you calculated this value I got: lead carbonate , 327.2 Do you know anything about this? aha @aaronq

OpenStudy (jfraser):

since lead is a transition metal, it has multiple "choices" for its oxidation state. You need to add a roman numeral to the name to be more specific. The molar mass is correct, however
