The previous systems of triple‐bond and single‐bond self‐consistent, additive covalent radii, R (AB)= r (A)+ r (B), are completed with a fit for σ 2 π 2 double‐bonds.The primary bond lengths, R , are taken from experimental or theoretical data corresponding to chosen group valencies. All r (E) values are obtained from the same, self‐consistent fit. Many of the calculated primary data came from ECH 2 and HECH 2 models. Homonuclear LEEL, formaldehyde‐type Group 14–Group 16 and open‐shell, X 3 Σ Group‐16 dimer data are included. The standard deviation for the 316 included data points is 3 pm.
