The covalent radii of transition metals decrease from left to right in a period because
- the densities of the metals decrease with increasing atomic number due to poor shielding of electrons
- the screening of nuclear charge by d electrons is poor and hence the nuclear charge attracts all the electrons strongly, causing a decrease in size
- the ionization energies also decrease correspondingly
- the metallic character decreases as the atomic number increases
Answer
(B) the screening of nuclear charge by d electrons is poor and hence the nuclear charge attracts all the electrons strongly, causing a decrease in size
