The quantum mechanical model of the hydrogen atom requires that if the principal quantum number is 5,there will be how many different permitted orbital quantum number(s)?
A) two
B) five
C) one
D) four

Question

Quizplus · Accepted Answer

The principal quantum number (n) determines the energy level of an electron in an atom. The orbital quantum number (l) determines the shape of the electron's orbital. For a given value of n, there can be n different values of l, ranging from 0 to n-1. Therefore, if n = 5, there can be 5 different permitted orbital quantum numbers.
