Question

Which of the following quantum number combinations is not allowed in a ground-state atom?

(7, 4, -2, -½)

(3, 0, 0, +½)

(2, 1, 1, -½)

(3, 2, 3, +½)

Answer 1

I don't think it's B or C

Answer 2

Answer 3

Is this in the order (n, l, ml, me)? I suppose?

Answer 4

If so, go through each carefully, look at the L and ml quantum numbers.
The magnetic quantum number (ml) goes from -L to +L.

Answer 5

I honestly don't know

Answer 6

Well, ok, the second number in each set is L, the angular momentum quantum number. The next number is ml, the magnetic quantum number.
ml can only have values from -L to +L.
So, if L was 3, ml can only go from -3 to 3.

Answer 7

then all are answers besides d?

Answer 8

LOL bunnies "(n, l, ml, me)" heheh ♥

Answer 9

Yesh Lena. && Lmao, what? ♥

Answer 10

No, wait. >.>
All can be quantum numbers, except D. Because ml has a value of 3, when L = 2

Answer 11

exactly that's what I meant sorry

Answer 12

You meant Ms heh

Answer 13

Silly wabbit. Quantum systems are for kids. xD

Answer 14

True. I meant ms.

Answer 15

I forgot what it was at first. Fight me doh.

Answer 16

Swing first homieee... I'm 2bach bihhhh

Answer 17
