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
