Question: Referring to Table 8.2 , explain why the first ionization energy of helium is less than twice the ionization energy of hydrogen, but the second

Referring to Table 8.2 , explain why the first ionization energy of helium is less than twice the ionization energy of hydrogen, but the second ionization energy of helium is greater than twice the ionization energy of hydrogen. [According to Coulomb's law, the energy between two charges Q1 and Q2 separated by distance r is proportional to (Q1Q2/r).]
