The energy corresponding to second line of Balmer series for hydrogen atom will be :-

Energy of electron in the first excited state of hydrongen atom is -3.4 eV . What is the kinetic energy of this electron ?

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) .

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