Question

Which of the following is a possible set of quantum numbers for an electron n, l, m subscript l, m subscript s ?

(1, 1, 0, +one over two )
(2, 1, 1, +one over two )
(3, 2, 3, -one over two )
(3, -2, 1, -one over two )

Answer 1

Assuming you know the rules for this, which option do you think is the answer?

Answer 2

I was just confused, haha XD

Answer 3

what are you confused about?

Answer 4

i'm not sure how to do it

Answer 5

Can you state the rules for quantum numbers?

Answer 6

it's not in my notes :(

n, can take on integer values n = 1, 2, 3, ...infinity
\(l\), only integer values between 0 and n-1 are allowed
\(m_l\), only integer values between -\(l\) and +\(l\) are allowed
\(m_s\), can have values of +1/2 or -1/2

Answer 8

I see.. what would we do next?

Answer 9

So you need to go through each option individually and see which of these follows the rules.
