 * Remember: periods are the rows on the table, groups are the columns! Families are like metals, Noble gases, etc.

Positively charged ions are positive because they are missing one or more electrons, and can mostly be found on the left side of the periodic table. Negatively charged ions have an extra electron, and are mostly on the right side of the table. Transition metals are in the middle of the table, and we cannot tell their charge by looking at the periodic table.**
