Why is there an increase in successive I.P values?
Why is there an increase in successive I.P values?
1. The minimum amount of energy required to remove an electron from the outermost shell of a neutral, gaseous atom is called Ionisation potential or Ionisation energy.
2. Ionisation energy values depend on the size of an atom, nuclear attraction and screening effect.
3. I.P values increase from left to right in a period and there is a gradual increase between successive elements due to the decrease in atomic size of atoms where as I.P decreases from top to bottom due to increase in atomic size.
4.As the valence electron enters into same shell, effective nuclear charge increases that result in the shrinking of the size of an atom and holds the outer electrons strongly. This require a large amount of energy to remove an electron. So, I.P increases in a period.
