The total number of orbitals associated with the principal quantum number n = 3 is

Options

A. 9
B. 8
C. 5
D. 7

Answer

a

Explanation

`n=3, l=0, m_(1)=0` - one s orbital
`n=3, l=1,m_(1)=-1,0,1` - three p orbitals
`n=3, l=2, m_(1)= -2, -1, 0, 1, 2` - five d Orbitals
Overall nine orbitals are possible.
