Which one of the following is true?
A) The principal quantum number of the electron in a hydrogen atom does not affect its energy.
B) The orbital angular momentum quantum number of an electron state is always less than the principal quantum number.
C) The electron spin quantum number can take on any one of four different values.
D) The principal quantum number of an electron in the ground state is zero.

Question

Quizplus · Accepted Answer

The orbital angular momentum quantum number (l) for an electron in an atom is always one less than the principal quantum number (n), making it always less than n. This means for any given n, l ranges from 0 to n-1.
