The more reactive an element, the stronger bonds it forms, because the same energy must be put in to that bond to separate them that was put out due to the reaction. Most of the elements we are made of, in pure form, are reactive correct? Carbon and oxygen have very high electronegativities, and Hydrogen is reactive as well. Therefore, shouldn't elements stop bonding after one or two reactions? For instance, lets make some HO. After the reaction is done, I am sure much energy was put into the reaction,due to both the elements being very reactive. So why is it that when another Hydrogen atom comes along, the HO will react with the lone H atom, if they are already in a stable state?
