Covalent radii (molecular triple bond): periodicity

This gives triple-bond covalent radii using specific group valencies and oxidation numbers.




This is a self-consistent system of additive covalent radii, R(AB)=r(A) + r(B), is set up for most elements of the periodic table, Z = 4+112. The primary bond lengths, R, are taken from experimental or theoretical data corresponding to chosen group valencies. All elements and all admitted data points are treated as equal. Radii were then obtained self-consistently through a least-squares fit. Specific molecular coordination numbers and oxidation states are chosen for each element involved.
