Explanation: For the same transition, The energies of stationary states for Hydrogen species like ( mathrm{He}^{2+}, mathrm{Li}^{2+} ) ( mathrm{Be}^{3+} ) etc are the integral multiples of ( Z^{2} ) times the energies of stationary states for Hydrogen atom. ( mathrm{Li}^{2+} ) ion ( = ) Atomic number ( =mathrm{Z}=3 ) The wave number of first Balmer line of ( mathrm{Li}+2 ) ion ( =mathrm{Z}^{2} mathrm{x} ) ( 15200 / mathrm{cm} ) ( =9 times 15200 ) ( =136800 / mathrm{cm} )
