Question

what do you mean by effective nuclear charge​

Answer 1

Answer:

Effective nuclear charge – the attractive positive charge of nuclear protons acting on valence electrons. The effective nuclear charge is always less than the total number of protons present in a nucleus due to shielding effect. Effective nuclear charge is behind all other periodic table tendencies.

Answer 2

Explanation:

The effective nuclear charge is the net charge an electron experiences in an atom with multiple electrons. The effective nuclear charge may be approximated by the equation: Zeff = Z - S. Where Z is the atomic number and S is the number of shielding electrons.
