Asked by celina

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
Answered by drwls
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.

what do the plus signs mean?
Answered by DrBob222
Ca++ means Ca<sup>+2</sup> or calcium ion with a +2 charge. Ca+++ means Ca<sup>+3</sup>.
