1.8 g hydrogen atoms are excited to radiation .The study of spectra indicate that 27% of the atom are in third energy level and 15 % of atom in second energy level and the rest in 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

According to MOT, two atomic orbitals overlap relsulting in the formation of molecular orbital. Number of atomic orbitals overlapping together is equal to the molecular orbital formed. The two atomic orbital formed by LCAO (linear combination of atomic orbital) in the same phase or in the different phase are known as bonding and antibonding molecular orbitals respectively. theenergy of bonding molecular orbital is less than that of the pure atomic orbital by an amount Delta . this is known as the stabilization energy. the energy of antibonding molecular orbital is increased by 'Delta' (destabilisation energy) The bond order of N_(2)^(-) is equal to that of

Total number of orbitals associated with third shell will be.....
