### Orbitals 1D.19

1D.19 How many orbitals are present in the (a) 4p-subshell; (b) 3d-subshell; (c) 1s-subshell; (d) 4f-subshell of an atom?

How would I go about doing this?

You only look at the lettered sub-shells not the number before, so S will always have 1, P has 3, D has 5 and F has 7 (you know this by drawing out the orbitals to place paired electrons in).

First of all, s-subshell is l=0, p-subshell is l=1, d-subshell is l=2, f-subshell is l=3
For (a), it is 4p-subshell, so l= 1. If l=1, ml can be -1, 0, 1.
Therefore, 4p-subshell can have 3 orbitals.
For (b), it is 3d-subshell, so l=2. If l=2, ml can be -2, -1, 0, 1, 2.
Therefore, 3d-subshell can have 5 orbitals.
(c) and (d) also have same mechanisms.
