Question

Explain Ionization energy and factors effecting it . Explain all factors in East way and lang.

Answer 1

Heya!
_____

____________________________________________________________
★Ionisation Energy ★
____________________________________________________________


→Ionization Energy I.E is the energy required to eject an electron form the surface of a neutral gaseous atom.


→Factors effecting ionization energy :
=================================


⭐Size of atom : As the due increases , the ionization energy decreases as the electrons get farther from the nucleus .


⭐Nuclear Charge : Ionization Energy increases with an increase in nuclear charge . I,e more energy with increasing charge.


⭐Penetration Effect : s > p > d > f . We know that s orbital is closest to the nucleus . Thus this arrangement is given as above .


⭐Screening / Shielding effect : The outer electrons shield the inner electrons. Thus, ionization energy decreases with the screening effect.


⭐Electronic Configuration : Half filled and fully filled configurations are more stable and hence needs high ionization energy.
