How do you determine the energy of a bond?

Usually the length (which correlates to strength) of a bond is a factor that determines the energy stored in a bond. These values are determined experimentally, however.

The energy of a bond is determined by measuring the heat required to break one mole of molecules into their individual atoms.

Bond Energy can be found by subtracting the sum of all the bonds formed from the sum of all bonds broken.

The energy of a bond that you are referring is probably the energy it takes to break a bond. In the very beginning, these values are experimentally observed. To calculate it, there is a formula: delta G = delta H - T*delta S, which we haven’t learned yet.

The formal energy is the difference between the number of valence electrons an atom normally has, and how many it has in a particular molecule. You can just count each dot individually, and then count only one electron for each bond (line).

I am confused by what formal energy is? is that formal charge?
