Why zeff greater than screening effect for sc, ti,vn,cr and Mn

Expert Answer:

In these elements outermost 4s electrons are shielded by inner 3d electrons. 3d electrons have poor shielding effect, so effective nuclear charge felt by only 4s electrons. So screening effect is lesser as compared to Z.
