Consider a gas consisting Li^(+2) (which is hydrogen like ion). (a) Find the wavelength of radiation required to excite the electron in Li^(++) from n=1 and n=3 . (Ionisation energy of the hydrogen atom equals 13.6 eV ). (b) How many spectral lines are observed in the emission spectrum of the above excited system?
A double ionised lithium atom is hydrogen like with atomic number 3 (i)Find the wavelength of the radiation to excite the electron in Li^(++) from the first to the third bohr orbit (lonisection energy of the hydrogen atom equals 13. 6) (ii) How many spectral lines are observed in the emission spetrum of the above excled system ?
The shortest wavelength spectral line in the brackett series of the spectrum of atomic hydrogen is the transition :
The third line of the Balmer series, in the emission spectrum of the hydrogen atom, is due to the transition from the
