Question

Define effective nuclear charge​

Answer 1

Explanation:

The effective nuclear charge (often symbolized as Zeff or Z*) is the net positive charge experienced by an electron in a multi-electron atom. The term “effective” is used because the shielding effect of negatively charged electrons prevents higher orbital electrons from experiencing the full nuclear charge.

Answer 2

The effective nuclear charge means net positive charge experienced by an electron in a polyelectronic atom. There are two factors responsible for increasing the effective nuclear charge, which is electrons and protons. The effective nuclear charge, Zeff=Z−S. this value gives information about the charge of an electron.
