Expert Solution
Step 1: Idea of effective nuclear charge

Effective nuclear charge is defined as the net charge on the nucleus which help to attract the electron towards the nucleus. 

Effective nuclear charge is calculated with the help of Slater rule 

    Zeff = Z- S 

where Z is atomic  number  and S is shielding constant.
