An electron near the nucleus has than an electron farther away.
a. more energy
b. less energy
c. more mass
d. more speed

less energy

Explanation:

an electron near the nucleus has less energy than an electron farther away because the closer the electron orbit is to the nucleus, the lower the energy level and therefore the lower the potential energy it possesses . when electrons move farther away, they move unto higher energy orbitals and therefore gain more energy.
