When an atom absorbs a(n) , which is a particle of electromagnetic radiation with no mass that carries a quantum of energy, it is excited from the , the lowest allowable energy state of an atom, to an excited state.

When an atom absorbs a(n) foton, which is a particle of electromagnetic radiation with no mass that carries a quantum of energy, it is excited from the , the lowest allowable energy state of an atom, to an excited state.

Explanation:

An atom does absorb a photon (elementary particle that carries forms of electromagnetic radiation), and said energy excites electrons from the atom, allowing it to pass from a minor to a higher level of nergy, this phenomenon being known as a transition.
