Question

covalent radius of 16th group​

Answer 1

Answer:

When two atoms of the same kind are bonded through a single bond in a neutral molecule, then one half of the bond length is referred to as the covalent radius. This is unambiguous for molecules such as Cl2, the other halogens, and for other cases such as hydrogen, silicon, carbon (as diamond), sulphur, germanium, tin, and a few other cases. However for oxygen, O2, the situation is less clear as the order of the oxygen-oxygen bond is double. In this case, and indeed for most of the periodic table, it is necessary to infer the covalent radius from molecules containing O-O single bonds or from molecules containing a C-X bond in which the covalent radius of X is known.
