An electron in an s state of an atom has an angular momentum quantum number of
A) 0.
B) 1.
C) 2.
D) 3.

Question

Quizplus · Accepted Answer

The angular momentum quantum number (l) for an s orbital is always 0. This is because an s orbital is spherically symmetrical and has no angular nodal planes. Angular momentum quantum number defines the shape of the orbital and gives information about its angular momentum and energy levels. Therefore, an electron in an s state of an atom has l = 0.
