Question

The maximum energy is present in any electron at- (A)nucleus (B)ground state (C)first excited state (D)infinite distance from nucleus

Answer 1

option:

(D)infinite distance from nucleus

Answer 2

Any electron has maximum energy when the electron is at (D) infinite distance from the nucleus.

Explanation:

This is because when an electron is attached to the nucleus with the help of mutual attraction between two different charges, it possesses negative and least energy. As the electron distances from the nucleus, the energy of the electron becomes less negative which means its energy increases.

When the electron is not under the attractive Coulomb force of the nucleus, all its energy is kinetic in nature and always positive.

This implies that farther the electron moves from nucleus, it has more energy.
