Question

What is effective nuclear charge​

Answer 1

Answer:

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 Z(eff at the down) = Z-S. Where Z is the atomic number and S is the number of shielding electrons.

Answer 2

Answer:

Effective nuclear charge : Due to screening effect the valency electrons experience less attraction towards nucleus. This reduces the active nuclear charge (z) actually present on the nucleus. This reduced nuclear charge is termed as 'effective nuclear charge. (Z_eff).
