Why is energy released when chemical bonds are formed?
-
I have seen plenty of articles stating that it is actually the forming of chemical bonds, not the breaking of them, that releases energy. Why does this happen, on the atomic scale. A cited source would be helpful since I am doing a science fair project. Thanks

Answer:
you can get a good quote from any chemistry text or try wikipedia energy is released when bonds are formed because the electrons involved move into a lower energy configuration in the bonded arrangement than they had before the bond formed

In all chemical change, chemical bonds are broken or formed. Energy is required to break a chemical bond (just as energy is required to stretch a spring until it breaks). Conversely, forming a chemical bond releases energy. Virtually all chemical reactions absorb or release energy because bond making seldom exactly balances bond breaking in the reaction.
