What is the difference between 2 hydrogen atoms and 1 hyrogen molecule?

Explanation:

H_2 rarr 2H*H22H

The standard state of elemental hydrogen is as the dihydrogen molecule, H_2H2. We could add energy to the LHS of the equation above and produce two hydrogen atoms as shown. The H*H radical is a highly reactive species - of course it could react with another H*H species (to form what), but it could also react with C-HCH or X-XXX bonds to form C*C and X*X radicals that continue the chain of reactivity.
