Vedclass · Answer

(D) The electronic configurations are:$_{20}Ca = [Ar] 4s^2$$_{21}Sc = [Ar] 4s^2 3d^1$$_{22}Ti = [Ar] 4s^2 3d^2$As we move from $Ca$ to $Ti$ across the period,the effective nuclear charge $(Z_{eff})$ increases because the $d$-orbitals have a diffused shape and provide poor shielding of the nuclear charge.Consequently,the atomic size decreases as the atomic number increases.The order of atomic size is $Ca > Sc > Ti$.Therefore,the order of increasing covalent radius is $(I) < (III) < (II)$.

Identify the correct order in which the covalent radius of the following elements increases: $(I) \ Ti, (II) \ Ca, (III) \ Sc$.
