Honors Chemistry A - Unit 3 : The Periodic Table (Extra Notes!)

ionic radius

• an extra thing to help w/ identifying which ion is greater, use these ideas

  • the order of ion size from greatest to smallest is: anion (-), neutral, cation (+)
  • when ordering the size of ions, first consider the charge of the ion
  • if it is an anion, it will be greater regardless of the # of electrons and vice versa
  • once the ions have been separated by charge, identify the # of electrons and sort from there
