The effective nuclear charge experienced by a valence electron is:

A.Equal to the atomic number

B.Always zero for transition metals

C.The nuclear charge minus the shielding effect of inner electrons

D.Equal to the mass number

Explanation

Effective nuclear charge (Zeff) = Z - sigma, where Z is the atomic number and sigma represents the shielding constant from inner electrons.

CThe nuclear charge minus the shielding effect of inner electrons
