if the molecule is not spherical. O2 and N2 are diatomic molecules (two atoms joined by a chemical bond or bonds), not spheres in shape but rather cylindrical in shape, akin to the shape of a tiny jelly bean. Thus, a "length" dimension of the cylindrical shape is a larger dimension than the smaller "waistline" diameter of the cylindrical shape.
Bond Length Values. Bond lengths have traditionally been expressed in Ångstrom units, but picometers are sometimes preferred (1 Å = 10-10 m = 100 pm). Bonds lengths are typically in the range of 1-2 Å, or 100-200 pm. Even though the bond vibrates, equilibrium bond lengths can be determined experimentally to within ±1 pm.

In molecular geometry, bond length or bond distance is defined as the average distance between nuclei of two bonded atoms in a molecule. It is a transferable property of a bond between atoms of fixed types, relatively independent of the rest of the molecule.This calculation yields the equilibrium bond length and the bond strength. Similarly, bond angles can be calculated by determining which angle gives the lowest energy. The energy released in a chemical reaction can be found by subtracting the energies of the products from the energies of the reactants.
