How does the energy of an electron change when the electron moves closer to the nucleus

 Potential energy decreases.

Explanation:  As we know that the electrons and nucleus are held together by the electrostatic forces of attraction due to nature of opposite charges of the same.

Thus when electron moves closer to the nucleus, the potential energy of the electron will decrease as the forces of attraction between the electrons and the  nucleus will increase thus providing overall stability to the system.

just did the assignment and the answer was #1 +2 n

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
