Explanation:
This contraction of nucleus makes the covalent radius smaller. ... Thus the metal ions are touching the electrons and are not like overlapping which is the case of covalent radii. Because of this the metallic radii of atoms is greater than the corresponding covalent radii of those metals.

Answer:
Explanation:
The main reason for why the van der Waals radius is greater than the covalent radius is that it does not take into account overlap. ... When two atoms form a covalent bond, their electron clouds overlap. In essence, that is what a covalent bond really is an overlap between orbitals.
