Why energy is liberated in bonding?

So here is the reason:

When 2 electrons make bond they stop at a position. Before making a bond they are revolving but when they stop the energy they have is liberated.

So it is reason why energy is given out when electrons make bond.

*this is true somewhat, It is my own idea. This can be useful to teach students. Why energy is liberated?
