An electron collides with a hydrogen atom in its ground state and excites it to $n$=3. The energy given to hydrogen atom in this inelastic collision is(neglect the recoiling of hydrogen atom)

(b) The energy taken by hydrogen atom corresponds to its transition from
$n$ =1 to $\ n =$3 state.
$\mathrm{\Delta}E\ \ \ (given\ to\ hydrogen\ atom)$
= 13.6 $\left( 1 - \frac{1}{9} ight)$
=13.6 $	imes \frac{8}{9}$ = 12.1 eV
