Document Summary

The bond length is the nuclear separation distance where a molecule is most stable (recall h2 at the beginning of this section). The smaller the atomic radii, the shorter the bond. Often, the higher the bond multiplicity, the shorter the bond. I. e. , a double bond is shorter than a single bond. The higher the effective nuclear charges of the bonded atoms, the shorter the bond.

The atomic radii influences the bond length more than the difference in electronegativity. The bond energy is the stability of a chemical bond. Bond strength increases as more electrons are shared between the atoms for c, Bond strength increases as the electronegativity difference (cid:894) (cid:895) (cid:271)etwee(cid:374) (cid:271)o(cid:374)ded atoms increases provided that the atoms are both in the same period. Bond strength decreases as bonds become longer.
