Question

what are the factors effecting ionisation energy of an atom​

Answer 1

Answer:



Size of atom (distance of outermost electron from the nucleus) As atomic size increases, the attraction of the positive nucleus for the negative electron decreases and less energy is required to remove an electron. This means that the ionisation energy decreases
