A double ionised Lithium atom is hydrogen-like with atomic number 3.
(i) Find the wavelength of the radiation required to excite the electron in Li++ from the first to the third Bohr orbit. (Ionisation energy of the hydrogen atom equals 13.6 eV .)
(ii) How many spectral lines are observed in the emission spectrum of the above excited system?
