An electron in H -atoms jumps from some higher level to 3rd energy level.If three spectral lines are possible for the transition, find the initial position of electron.

Text Solution

Verified by Experts

The correct Answer is:
6
`x+e^(-) rarr x^(-)`
energy released =`E.A_(1)+E.A_(2)=30.87 eV//atom`
Let no. of moles of `X` be a
`:. axxN_(a)xx30.87=6xxN_(a)xx4.526+6xxN_(a)xx13.6+6xxN_(a)xx12.75 rArr a=6 `moles
