Atomic hydrogen combaines with almost all elements but molecular hydrogen does not. Explain.

Explanation

Atomic hydrogen is formed by passing hydrogen gas through lungsten electrodes at `2000 "to" 3000^(@)C` and under low pressure. This means that energy associated with atomic hydrogen is more than energy associated with molecular hydrogen. Therefore, atomic hydrogen is more reactive and combines.
