Be sure you can predict ion formation from the previous module. (In other words--what is the charge expected when an atom forms an ion). Remember an ion is a charged particle that results from the loss or gain of 1 or more electrons. The number of electrons that an atom will lose or gain is based on its group number from the periodic table. Ca N Li Br S Al
