write a chemical equation for an atom losing a third electron. would the ionization energy for this reaction be larger or smaller that the ionization energy for the lloss of the first or second electron? explain

  • chemistry -

    Ca++ -> Ca+++ + e-

    The ionization energy would be higher than it would be for the second electron, because there are fewer other electrons around to shield the nucleus.
