How can an electron in an atom lose energy to go from a higher energy level to a lower energy level?
A)It releases a photon equal in energy to its own energy drop.
B)It loses gravitational potential energy.

D)It exchanges gravitational potential energy for kinetic energy.
E)It loses kinetic energy.

Question

Quizplus · Accepted Answer

When an electron in an atom transitions from a higher energy level to a lower one, it emits a photon whose energy is equal to the difference in energy between the two levels. This process is a fundamental principle of quantum mechanics and is key to understanding phenomena such as atomic emission spectra.
