Comments

For chemical elements there are single-, double- and triple-bond covalent radii. This sequence uses single-bond covalent radii. If the data for two elements are the same then they are sorted by atomic number (for example, the data for titanium (22) and cadmium (48) are both 136 pm so 22 comes before 48). - Jianing Song, Oct 01 2018

Example

The elements with the smallest covalent radii are hydrogen (1), helium (2), oxygen (8) etc.
