When energy in the atom is released what occurs

What happens when electrons in an atom absorb or release energy, their electrons can move to higher or lower energy levels.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
