When is the energy of electron regarded as zero ?

Text Solution

Verified by Experts

The energy of the electron is regarded as zero when it is at infinite from the nucleus. At that point, the forces of interaction between the electron and the nucleus are almost nil. Therefore, its energy is regarded as zero.
