Question

By bohor model ionization energy of hydrogen

Answer 1

The IE of HH from its ground state (n=1n=1) is 1312 kJ/mol1312 kJ/mol. Because of the squaring of the principle energy level, the ionization of an e−eX− in HH from the n=2n=2level is 1/41/4 of that value (328 kJ/mol328 kJ/mol). The transition energy from the n=1n=1 level to n=2n=2 level is the difference between the two values, 984 kJ/mol984 kJ/mol.
