An electron in H atom jumps from the third energy level to the first energy .The charge in the potential energy of the electron is

Options

A. `12.09 eV`
B. `6.04 eV`
C. `42.18 eV`
D. None

Explanation

`TE = -KE = (1)/(2) PE`
`PE_(1) = 2TE_(1) = 2 xx -13.6 eV = - 27.2 eV (first orbit)`
`PE_(1) = 2TE_(3) = 2 xx (-13.6)/(9)= (-227.2)/(9)eV`
`PE_(3) = PE_(1) = (-27.2)/(9) -(27.2)`
`= 27.2 xx (8)/(9) = 24.18 eV`
