Question

Effective nuclear charge (Z*) can be calculated by using the formula
a) Z* = Z – S
b) Z* = Z + S
c) Z* = S – Z
d) Z = Z* – S

Answer 1

Effective nuclear charge (Z*) can be calculated by using the formula:

Correct Option is : a

        Z* = Z – S

Explanation :

The effective nuclear charge . Represented by Zeff is the net positive charge experienced by an electron in a muti electron atom.The effective nuclear charge on the electron is given by the equation :

Zeff=Z-S
where Z is the number of protons in nucleus

S= is the number of electrons between nucleus and electron ( number of non valence shell electrons].
