Which of these statements about electron energy levels in hydrogen atoms is true?
A) An electron with a positive total energy is a bound electron.
B) The orbital angular momentum of an electron in the ground state is zero.
C) An electron in the hydrogen atom is best represented as a traveling wave.
D) An electron in state n can make transitions only to the state n + 1 or n − 1.

Question

Quizplus · Accepted Answer

The ground state of hydrogen is when the electron is in the lowest energy level, n=1. In this state, the electron has zero orbital angular momentum, which means it is not moving around the nucleus at all. Choices A, C, and D are all incorrect.
