What can you assume has happened if an electron moves to a higher energy level? A) the atom has become more stable

Bthe electron has lost energy
Cthe electron has gain energy
Dthe atom has lost an electron

Verified Answer :

Answer:C) the electron has gain energy

Explanation:

electron can move to a higher energy level only if it gains energy by gaining energy photon. in this case atom becomes unstable. in order to loos the electron a minimum amount of energy required called work function. Here electron only moves to higher energy state so atom will come in the excited state and after loosing the same amount of energy atom comes back into the ground level.
