%N Atomic numbers of the chemical elements sorted with respect to single-bond covalent radius.

%C 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 sortedby 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
