Question

When an electron in a hydrogen atom makes a transition from an excited state to the ground state, its kinetic energy increases, its potential energy decreases and its total energy remains constant.

• A. True
• B. False

Answer 1

The correct option is B False

When an electron in a hydrogen atom makes a transition from an excited state to the ground state, it is losing energy. To conserve energy, a photon with an energy equal to the energy difference between the states will be emitted by the atom.
