In H-atom electron jumps form 3 to 2 energy level, the energy released is

Answer»

`3.03xx10^(-19)` J/atom
`1.03xx10^(-19)` J/atom
`3.03xx10^(-12)`J/atom
`6.06xx10^(-19)`J/atom

Solution :`DeltaE` (energy RELEASED)`=E_(3)-E_(2)`
`=-1311.6/(3^(2))-(-1311.8)/(2^(2))` kJ MOL
`=1311.8(1/4-1/9)XX(10^(3))/(602xx10^(23))` J/atom
`=3.03xx10^(-19)`J/atom
