Covalent radii

Postby Amy Lefley 1J » Mon Nov 12, 2018 11:19 pm

Covalent radii, to my understanding, is the covalent bond length which is the sum of the two atom's radii. Isn't this assuming that there is no space between the atoms in the bond or is it just that the space is negligible?

From my understanding, the fact that the bond is covalent, the bonds must be touching. They share a pair of electrons, so that means we do assume their is such space between the two.

Actually thats incorrect. Covalent radii is half the distance between the two nuclei. It isn't the sum of the two radii at all. When the two atoms bond the like kinda mesh together so yea its just half the distance between not the sum.
