Question

When an electron moves away from the nucleus in an atom?

Answer 1

when it moves away from the nucleus means the electronegativity of an atom is more :means that the nuclearpupll of that atom is less

Answer 2

Answer:

As electrons move farther away from the nucleus, they gain potential energy and become less stable.

Explanation:

Atoms with electrons in their lowest energy orbits are in a "ground" state, and those with electrons jumped to higher energy orbits are in an "excited" state.
