Question

explain why van der waals radii always larger than covalent radii

Answer 1

This is because van der walls radii is for noble gases and we all know that noble gases have the biggest size among all elements as they are neutral and are stable with valence electron completely filled.so van der walls radii is always larger than covalent radii.

Answer 2

Hey dear,

● Explanation -
- Covalent radius is half the internuclear distance of two single-bonded atoms of same species.
- Van der Waal's radius is half the distance between two closest non-bonded atoms of same species.
- As intermolecular distance is always greater that bond length, van der Waals radius is greater than covalent radii.
