Predicting the bond strength by radius
The strength of a bond can be estimated by comparing the atomic radii of the atoms that form the bond to the length of bond itself. For example, the atomic radius of boron is estimated at 85 pm, while the length of the B–B bond in diboron tetrachloride, B2Cl4 is 175 pm. Dividing the length of this bond by the sum of each boron atom's radius gives a ratio of
