Question

Suppose you take a trip to a distant universe?...
You find that the periodic table there is derived from an arrangement of quantum numbers different from the one on Earth. The rules in that universe are:
1. principal quantum number n = 1, 2, . . . (as on Earth);
2. angular momentum quantum number ℓ = 0, 1, 2,. . . , n – 1 (as on Earth);
3. magnetic quantum number mℓ = 0, 1, 2, . . . , ℓ (only positive integers up to and including ℓ are allowed);
4. spin quantum number ms = –1, 0, 1 (that is, three allowed values of spin).

Answer 1

(a) Assuming that the Pauli exclusion principle remains valid, what is the maximum number of electrons that can populate a given orbital?

(b) Write the electronic configuration of the element with atomic number 8 in the periodic table. (Formatting: superscript numbers where appropriate but omit parentheses.)

(c) What is the atomic number of the second noble gas?


I already have a) and c) I think .. but I can't figure out how to do b) ??? please help

Answer 2

I believe the answer to A is three. 12 electrons, you have the n,l, and mL's (3) AND -1,0, and +1

for B. the idea is that you don't pair up electrons until all the mL's have 1.

(2, 1, 0, +1) - (1st)
(2, 1, 0, 0) - (3rd)
(2, 1, 0, -1) - (5th)
and then,
(2, 1, 1, +1) (2nd)
(2, 1, 1, 0) - (4th)
(2, 1, 1, -1) - (6th)

Answer 4

That still makes no sense to me. :(

Answer 5

1) 2 electrons
2) 1s2,2s2,2p6
3)10

Answer 6

No that would be correct for our real periodic table... but not for this

Answer 7

omg. i just realized ur name, @chmvijay so hardcore and NC-17 rated.

Answer 8

I thought the answer might be 1s^3 2s^3 2p^2?? ... but i don't know

Answer 9

hey what do you mean by NC-17 @abb0t

Answer 10

sorry idont know the new rules and the way we have to write@cntrywrtr

Answer 11

I understand like the real rules .. but this "other universe" crap is soooo confusing. :( I only 1 more try to get it right for full credit
