Ionization energy for He gas tubes

    Could we ionize He also if it has the biggest ionization energy?

    Yes, we could - provide an energy of 24.6 eV to an He atom, and it will say goodbye to one of its electrons. And even if WE could not do so for whatever reason (stupidity ? laziness ?) our sun does this to its He atoms.
