The quantum number n of the lowest energy state of a hydrogen atom
A) is 0.
B) is 1.
C) depends on the orbit size.
D) depends on the electron speed.

Question

Quizplus · Accepted Answer

The lowest energy state of a hydrogen atom corresponds to the ground state, which has a principal quantum number of 1. The other options given are incorrect: there is no orbital state with a principal quantum number of 0 in hydrogen, and the principal quantum number does not depend on the electron's speed.
