Question

What is screening effect how does it govern the ionization enthalpy of an atom​

Answer 1

the effect of innercore of electrons on nuclear attraction towards nuclear attraction is known as screening effect. If screening effect increases the nulear attraction towards valence electrons decreases.so low amount of energy is required to remove valence electrons. That means ionisation enthalpy decreases

Answer 2

Answer:

Effect of inner core of electrons on nuclear attraction towards nuclear attraction is called as screening effect.

If screening effect increases the nuclear attraction towards valence electrons decreases.so low amount of energy is required to remove valence electrons. That means ionization enthalpy decreases.
