quantum theory

The color of light depends on how far the electron falls.

A big drop in energy level results in violet light.

A small drop in energy level results in red light.

Electrons absorb energy and fall to a lower orbit.

Electrons are emitted from a metal surface when light of a certain frequency shines on it.

Electrons move in fixed orbits around the nucleus.

Atoms emit light only when heated to high temperatures.

Electrons can exist anywhere around the nucleus.

It jumps to a higher energy orbit.

It emits a photon and falls to a lower orbit.

It becomes a proton.

It leaves the atom completely.
