On the basis of electronic conbept, justify that the following reaction is a redox reaction `2Na(g)+H_(2)(g)rarr2NaH(s)`

Answer» In terms of electrons concept, the reacion may be split into oxidation half reaction (loss of electrons ) and reduction half reactin (gain of electrons)
`2Na(s)rarr2Na+(g)+2e^(-)`(oxidation half reaction)
`H_(2)(g)+2e^(-)rarr2H^(-)(g)`(reduction half reaction)
The given reaction is therefore, a redox reaction in nature.
