If radiation corresponding to first line "Balmer series" of `He^(+)` ion is subjected to a sample of `Li^(+2)` ion (containing atoms in different energy states) and it causes ejection of photo electron with non-zero kinetic energy then calculate least shell number in which the electron must be present in `Li^(+2)`.

Answer

5

Explanation

`13.6xx2^(2) (1/(2^(2))-1/(3^(2))) gt 13.6 xx(3^(2))/(n^(2))`
`n gt 4.1 " " , " " n=5`
