Electrons exist only at fixed levels of potential energy. however, if an atom absorbs sufficient energy, a possible result is that

Answer;

-An electron may move to an electron shell farther away from the nucleus.

Explanation;

-Kinetic and potential energy of atoms result from the motion of electrons. When electrons are excited they move to a higher energy orbital farther away from the atom. The further the orbital is from the nucleus, the higher the potential energy of an electron at that energy level.

-When the electron returns to a low energy state, it releases the potential energy in the form of kinetic energy.
