Explanation:
Detailed explanation-1: -The ionisation energy of Hydrogen atom in the ground state is 13.6 eV. Ionisation energy is the amount of energy required to remove the most loosely held electron or valence electron from the atom. Was this answer helpful?
Detailed explanation-2: -The ionization energy of hydrogen atom is 1314 kJ mol−1.
Detailed explanation-3: -Hence, the energy required to bring an electron in H atom from ground state to second excited state is 12.09 eV.
Detailed explanation-4: -Hence, Using the Rydberg expression, the Ionization energy of a hydrogen atom in its ground state can be calculated to be 1312 kJ mol-1 .
