As an electron moves away from the nucleus, its potential energy
0.Increases
1.Decreases
2.Remains constant
3.First increases then decreases
Explanation
Potential energy of electron = −Ze²/(4πε₀r). As r increases (moving away from nucleus), PE becomes less negative (increases, approaching zero). PE is always negative but increases toward zero as distance increases.
