if an atom is supplied with excess energy:

a proton will leave the nucleus
an electron may change to an excited state
an electron may fly off (exit) the energy level
an electron may move to a higher energy level
an electron may move to a lower energy level

Option (d) is the correct answer.

Explanation:

When we supply energy to an electron then on absorption of energy it moves 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 if an atom is supplied with excess energy then an electron may move to a higher energy level.
