Covalent Radii

How do you find the Covalent Radii of two atoms?

You just add together half the distance of each diameter of each atom in the covalent bond.

Covalent radii typically decrease from left to right across a period. This is because the increasing effective nuclear charge draws in the electrons and makes the atom more compact, similar to the trend for atomic radii. Also like atomic radii, covalent radii increase down a group because the valence electrons occupy shells that are farther from the nucleus so there is greater shielding by the inner core of electrons.
