The energy level of an atom for 1 ^(st),2 ^(nd) and third levels are E, 4E, 2E respectively. If photon of wavelength lamda is emitted for a transition 3 to 1. Calculate the wavelength for transition 2 to 1 in terms of lamda.

1.8 g hydrogen atomic are excited to radiation .The stady of specits indicate that 27% of the atom are is third energy level and 15 % of atom in second energy level and the rest is ground state IP of H is 13.6 eV calculate a. Number of atom present in first and third energy levels b. Total energy envolved when all the atom return to the ground state

For He^(Theta) and Li^(2+) , the energies are relased to the quantum number n through an expression E_(n) = (Z^(2)B)/(n^(2)) where Z is the atomic number species and B = 2.179 xx 10^(-19) J a.What is the energy of the lowest level of a He^(Theta) ion ? b. .What is the energy of the third level of a Li^(2+) ion ?
