What is the smallest energy photon that a hydrogen atom in the ground state can absorb?
A) any energy
B) 13.6 eV
C) 10.2 eV
D) 3.40 eV
E) 1.90 eV

Question

Quizplus · Accepted Answer

The smallest energy photon that a hydrogen atom in the ground state can absorb corresponds to the energy difference between the ground state (n=1) and the first excited state (n=2), which is 10.2 eV. This transition is necessary for the electron to jump from the ground state to a higher energy level.
