Singly Ionized Helium Definition Singly ionized helium is an atom with one of its electrons missing. Assume that the remaining electron would behave like an electron of hydrogen. There is only one distinction between an atom of hydrogen and a single ionized atom of helium; the number of protons in the nucleus, hence the nuclear charge. (Pickering Series) E.C. Pickering discovered ionized helium lines in the hot star Zeta Puppis in 1896, and mistaked it for a form of hydrogen. Later these lines are found in other hot emission line stars and Wolf-Rayet stars. Pickering was convinced that the lines were due to hydrogen under unknown temperature and pressure conditions. A singly ionized helium atom (He^+) has only one electron in orbit about the nucleus. What is the radius of the ion when it is in the excited state defined by n=2? (answer in m) Study.com. Doubly ionized helium atom. Ionization of the most abundant elements, hydrogen and helium, is important for the equation of state. For these elements we have: ionization of hydrogen: χ = 13.54 eV, 2gi+1/gi = 1, first ionization of helium: χ = 24.48 eV, 2gi+1/gi = 4, second ionization of helium: χ = 54.17 eV, 2gi+1/gi = 1. Consider now pure, partly ionized hydrogen. Singly ionized helium is an atom that has lost one of its electrons. We must expect its remaining electron to act like a hydrogen electron. There is only one difference between a hydrogen atom and a singly ionized helium atom; number of protons in the nucleus, so the nuclear charge.
