Covalent radius: the nominal radius of the atoms of an element when covalently bound to other atoms, as deduced from the separation between the atomic nuclei in molecules. In principle, the distance between two atoms that are bound to each other in a molecule (the length of that covalent bond) should equal the sum of their covalent radii. [13]

[29] They also classify an exercise as extremely heavy if oxygen consumption is higher than 2.0L min −1.
