When two free hydrogen atoms come near each other, there will be an attractive force between the nucleus of first atom and electron of second atom and makes it to combine. Similar attractive force exists between nucleus of second hydrogen atom and electron of first hydrogen atom. Thus, it forms the hydrogen molecule and energy of about 430 KJ/mol is released.
Hope it helps.
