Question

Which of the following is a possible set of quantum numbers for an electron?

(1, 0, 0, +1)

(2, 2, 1, +½)

(4, -3, 0, -½)

(3, 2, 1, -½)

Answer 1

I think it's A or D

Answer 2

Electrons can only have one type of spin, + or - 1/2.

Answer 3

So it's D?

Answer 4

Yep, assuming your reasoning behind eliminating B and C is sound.

Answer 5

Well isn't it n, n-1,

Answer 6

2-1 isn't 2, and 4-1 isn't -3

Answer 7

Yeah, the second value is wrong for both B and C cause you can't have it be the same as your principal quantum number or be negative. You can have a negative orbital angular momentum or electron spin though, since that's just a direction rather than referring to energy which is positive or a shape, s,p,d or f.

Answer 8
