4 What is the total number of orbitals in a sulfur atom which contain at least one electron?
A 3
B 5
C 8
D 9
ANSWER
D 9
Analysis of Option/Explanation
First we should know the atomic number of Sulfur, which are 16. Hence, its electronic configuration is as follows:-
1s2, 2s2, 2p6, 3s2, 3p4
Secondly, we know that Sub shell “s” has 1 orbital, Sub shell p has 3 orbital, hence counting for it makes as
1s2, 2s2, 2p6, 3s2, 3p4
orbital→ 1, 1, 3, 1, 3, total = 9 orbital
