Question

What happenes when an election moves to a higher energy level?

Answer 1

The electrons in an atom exist in various energy levels. When an electron moves from a lower energy level to a higher energy level, energy is absorbed by the atom. When an electron moves from a higher to a lower energy level, energy is released (often as light).

Answer 2

Do you mean electron, if an electron moves to higher energy level then it has low electronegative and its hard for that element to lose an electron. Atomic radius increases
