Question

what do you understand by vanderwal radius and covalent radius.​

Answer 1

Answer:

The covalent radius, rcov, is a measure of the size of an atom that forms part of one covalent bond. It is usually measured either in picometres (pm) or angstroms (Å), with 1 Å = 100 pm. In principle, the sum of the two co equal the covalent bond length between two atoms, R(AB) = r(A) + r(B).

• Covalent radius: Covalent bond radius refers to half of the distance two singly bonded atom of the same element.

• Van der Waals Radius: It is defined as half of the internuclear separation of two non- bonded atoms of the same element on their closest possible approach.
