I can define and give an example of an ionic compound. Are formed by the combining of metals and non metals, and by the transfer of electrons. Metal atoms give electrons, while nonmetal atoms receive electrons. The compound formed is electrically neutral. Step 1: Write the symbol with the metal first. Step 2: Write the ionic charge above each symbol. Step 3: Write the ionic charges above the symbols for the elements and crisscross the numbers writing them as subscripts. Aluminum & Sulfur Sodium & Bromine Potassium and Oxygen Potassium Sulfate Ammonium Carbonate Iron (III) Oxide Sodium chloride Lithium sulfide Silver Carbonate The name of the metal comes first followed by the name of the nonmetal. The ending of the nonmetal changes to “ide”. MgCl2 Na3P AlBr3 Mg(CO3)2 FeCl3 I can define and give an example of an ionic compound.
