An electron has a spin quantum number `+1(1)/(2)` and a magnetic quantum number -1. It cannot be present in

Options

A. d-orbital
B. f-orbital
C. p-orbital
D. s-orbital

Answer

D

Explanation

(d) Spatial orientation of the orbital with respect to standard set of cordinate axis. Magnetic quantum number -1 is possible only when the azimuthal quantum number have value l=1, which is possible for p, d and f-subshells but not for s-subshell because the value of l for s-subshell is zero.
