Calculate the energy emitted when electron of 1.0 gm atom of Hydrogen undergo transition giving the spectrtal lines of lowest energy is visible region of its atomic spectra. Given that, `R_(H)`=`1.1xx10^(7) m^(-1)`,` c=3xx10^8m//sec`,` h=6.625xx10^(-34) Jsec`.

Text Solution

Verified by Experts

The correct Answer is:
`182.5 kJ`
`E=13.6[1/n_(1)^(2)-1/n_(2)^(2)]eV//atom rArr E=13.6[(9-4)/36] eV//atom`
`E=13.6[(9-4)/(36)]xx6.023xx10^(23)xx1.6xx10^(-19) rArr 182.5 kJ`
