What is this? i dont understand! *delete me*

Which of the following is the correct set of quantum numbers for an electron in a 3d orbital ?

a)   n = 3       l = 2       ml = −2       ms = +1/2

b)   n = 3       l = 2       ml = 3       ms = −1/2

c)   n = 2       l = 2       ml = 2       ms = +1/2

d)   n = 2       l = 3       ml = −2       ms = +1/2

Here are some questions to consider:

1)  What does the "3" stand for in the 3d orbital's name?  Specifically, which quantum number does it describe?

2)  What does the "d" stand for in the 3d orbital's name?  Which quantum number does it describe?

3)  Only certain values of m_l are allowed.  What rule governs the allowed values of m_l?

If you don't know the answer to these questions, you should look them up in your chemistry textbook or try a google search.
