Question

what is the ionization energy of hydrogen and how is it calculated?

Answer 1

To find the normally quoted ionization energy, this value is multiplied by the number of atoms in a mole of hydrogen atoms (the Avogadro constant) and then dividing by 1000 to convert joules to kilojoules. This compares well with the normally quoted value for hydrogen's ionization energy of 1312 kJ mol-1
