The energy required to remove one mole of electrons from one mole of gaseous atoms to form one mole of ions with a single positive charge is called the first ionisation energy.. Appendix B The Ionisation Energy Diagnostic Instrument (IEDI) Choose the most suitable option and the reason for your choice in each question by filling the appropriate circles in the answer sheet.
