Covalent radius

Covalent radius denotes half of the distance between two atoms of the same chemical element, which are covalently bonded. This radius depends on the type of bond (single, double or triple bond) from, and of the electronegativity with different binding partners.

A further distinction is the atomic radius and the van der Waals radius.
