What happens when an electron moves to a higher energy level?

the atom loses the electron.

the atom becomes more stable.

the electron gains energy.

Option (c) is the correct answer.

Explanation:

When energy is supplied to an electron then on absorption of energy it tends to move from a lower energy level to higher energy level.

And, when this electron moves from higher energy level to lower energy level then excess of energy absorbed by it is released in the form of visible light or radiation.

This emission of energy is also responsible for imparting color to a compound.

Thus, we can conclude that electron gains energy when an electron moves to a higher energy level.
