Pick 3 metals and 3 nonmetals and do the following:

  1. Write the symbol of the atom and how many electrons it has
  2. Write the symbol of the ion and how many electrons it lost or gained
  3. Label the ion as a cation or anion
  4. Create 9 compounds with your 6 ions and write their formulas and their names.

Example: 1 metal = Barium and 1 nonmetal = Astatine

  1. Ba = 56 electrons and At = 85 electrons
  2. Ba2+  lost 2 electrons    and    At1-    gained 1 electron
  3. Ba2+  is a cation    and    At1-    is an anion
  4. formula = BaAt and the name is Barium Astatide
