Atoms of the transition elements are smaller than those of the s-block elements, because:

Threre is increase in the cuclear charge along the period

orbital electrons are added to the penultimate d-subshell rather than to the outer shell of the atom

the shielding effect of d-electrons is small.

All of these.

The correct Answer is:

The atomic radii of the transition metals lie in-between those of s- and p-block elements. In the beginning, the atomic radius decreases with the increase in nuclear charge (as atomic number increases), whereas the dhielding effect of d-electronic is small and orbital electrons are added to the penultimate d-subshell rather than to the outer shell of the atom.

Atoms of the transition element are smaller than those of the s-block elements, because :

there is increase in the nuclear charge along the period.

orbital electrons are added to the penultimate d-subshell rather than to the outer shell of the atom.

All of these.

The melting points and the boiling points of the transitions elements are higher than the corresponding s-block elements. This is because

Transition metals have smaller size

Of the presence of one or more unpaired electrons contribution to higher inter atomic forces on account of covalent bond

of strong metalic bond due to small size and higher ionization energy

of the presence of vacant d-orbitals
