in my opinion, wikipedia is not a good site.
bond length is the, obviously, length of a bond between the nuclei of two nuclei. the larger the atom, the larger the bond length and therefore, the less stable the molecule can be.
for example, NaCl and NaI are both ionic. NaCl has more ionic character than NaI because I is so much bigger than Cl. when Na binds Cl it has a bond length of x. with Br, the Na-Br bond length is >x since Br is a much bigger atom than Cl.
the shorter the bond length, the more energy it will take to break that bond. for example. the C-C bond has less bond strength and length than the C=C bond and much less than the triple bonded C atoms.
the bonds between 2 atoms is the potential energy of the bond. it is negative potential energy since it takes energy to break the bond. a strong bond will have much more negative potential energy than a weaker bond. for a short bond length and thereby a strong bond, it takes much more energy to be put into the bond to return the individual atoms to 0 potential energy.
