The first ionization energy for H, He, Li and Be has one of the following values : 5.4, 9.3, 13.6 and 24.6 eV. Which of these values is correct for hydrogen?

Answer: 13.6

Solution

The standard first ionisation energies are: Li ≈ 5.4 eV, Be ≈ 9.3 eV, H ≈ 13.6 eV, and He ≈ 24.6 eV (He being a noble gas has the
