For an electron to move away from the nucleus....

• the atom must absorb energy because the electron is moving against an attraction

• the atom must absorb energy because the electron is moving against a repulsion

• the atom must release energy because the electron is moving against an attraction

• the atom must release energy because the electron is moving against an repulsion
