When the azimuthal quantum number has the value `2`, the number of orbitals possible is

Options

A. 3
B. 0
C. 7
D. 5

Answer

D

Explanation

Total values of `m=(2l+1)` = no. of orbitals in subshell.
Where m = Magnetic quantum no.
l = Azimuthal quantum no.
where l = 2 represents ‘d’ subshell and d-subshell has five orbitals. `(d_(xy),d_(yz),d_(zx),d_(x^(2)-y^(2)),d_(z^(2)))`.
