I can't get the answer, pls help!!! And explain how the answer came too pls. Need quickly!!!
Solution:
Option A is correct.
In the beginning of 3d series from Sc to Cr, effective nuclear charge (Zeff) > Screening effect. Since there are fewer d-electrons in 3d subshell
As a result there is a gradual decrease in atomic radii.
Sc>Ti>V>Cr
