Question

Why energy of electron inside an atom is negative?

Answer 1

Answer:

Please mark this answer as the brainliest

Explanation:

It is because when an electron is at infinite distance from nucleus , there the kinetic energy of that electron can not be calculated.

So, it is taken to be zero . when that electron comes close to nucleus, the stability increases due to loss of energy of electron. And thus the energy of electron becomes less negative . That's why the electron's energy is taken as negative.

Answer 2

Explanation:

electron...some repulsions from the nucleus......so negetive charge................
