Where on the periodic table would you find elements that ionize to form cations and anions?????
Metal ions lose electrons to form cations, nonmetal ions gain electron to form anions.
All elements on the table are trying to get to the 8th column. Metals on the periodic table lose electrons. An example is aluminum. Aluminum needs three in order to reach the far right of the table. Don't move right, count three to the left. So you write Al +3. This is a cation. Nonmetals gain electrons. An example is sodium. Once again go left, count 1. This is written as Na +1 and is a anion. I hope this helps. I'll explain more if you need it.
