Question

The glowing of a neon light is caused by electrons emitting energy as they (1 point)
move from lower to higher energy levels.
collide with other electrons.
move from higher to lower energy levels.
collide with the nucleus.

Answer 1

Electrons get excited to some higher energy level by a source of energy, like an electric field.

Very soon afterward, the electron is deexcited, dropping from a higher energy level to a lower one. If the electron gained some amount of potential energy by moving up to the higher energy level, it must lose some of that potential energy when it drops back down to a lower energy level. This loss of energy is given off as light.
