Effective nuclear charge ( 
) for a nucleus of an atom is defined as.
Text Solution
Verified by ExpertsThe correct answer is:
B
The effective nuclear charge 
is the net positive charge experienced by an electron from the nucleus in a polyelectronic atom. The term "effective" is used because the shielding effect of negatively charged electrons prevents higher orbital electrons from experiencing the full nuclear charge of the nucleus due to the repelling effect of inner-layer electrons.
