Today students learned about ionic bonds, how to bond them, and how to name ionic compounds.Ionic bonds are formed by ecriss crossing the charges of a cation and anion.
Students lined up in the hallway and went on "speed dates" with members of the opposite charge, came up with the correct formula, and then named the resulting compound.

Now in the usual speed dating format, ask metals (or non-metals) to sit at desks whilst the others circulate round with their profiles.
They have 5 minutes with each other before a bell is rung and they move on. During each ‘date’ each element should inspect each other’s profile and fill in a compatibility sheet.
About 20 percent of them do not exist in nature (or are present only in trace amounts) and are known only because they have been synthetically prepared in the laboratory. The number of possible compounds is almost infinite; perhaps a million are known, and more are being discovered every day.
When two or more elements combine to form a compound, they lose their separate identities, and the product has characteristics quite different from those of the constituent elements.
