Question

Electron present in single electron specie jump from energy level 3 to 1 .Emitted photons when passed
through a containig excited He^(+) ino cause further excition to same higher energy level (Given
`E_(n)=-13.6(Z^(2)/(n^(2)))`.Determine
(i) Atomic number of single electron specie.
(ii) principle quantum number of inital excited level & higher energy level of `He^(+)`.

Answer 1

Correct Answer - (i) `Z=5`, (ii) For `He^(+)` ion this energy corresponds to excitation from 2 to 6.
