1. IONic Bonding EQ: How do simple and complex ionic compounds relate to anions and cations?

2. Ionic Compounds  Occur between METALS and NONMETALS  Happens when electrons are transferred from one atom to another.  Example: NaCl (Sodium Chloride)  Non-Example: H 2 O

3. Ionic Compounds  When atoms gain or lose electrons, atoms are no longer NEUTRAL.  They become IONS with CHARGES.  The compounds that form in this way are called IONIC COMPOUNDS.  IONIC COMPOUNDS are very stable.

4. CATIONS  As previously stated, ionic compounds form between metal atoms and nonmetal atoms.  Metals on the left side of the periodic table give up electrons and become CATIONS.  CATIONS are positively charged Ions. These occur when there are more protons than electrons in an atom.

5. ANIONS  The nonmetal atoms on the right side of the periodic table tend to accept electrons and become ANIONS.  ANIONS are negatively charged atoms. This occurs when there are more electrons than protons in an atom.

6. Using the Periodic Table  How can we use the periodic table to predict IONIC COMPOUNDS? What is an example of a simple ionic compound? We know that in order to form ionic compounds we need a metal and a nonmetal. We use the periodic table to identify potential metal/nonmetal combinations through our knowledge of their location on the chart. NaCl – Sodium 1 + Chlorine 7 = 8 Valence electrons BeO – Beryllium 2 + Oxygen 6 = 8 Valence electrons

7. Using the Periodic Table  What is an example of a complex ionic compound? Na 2 O – 2 Sodium 1 (2) + Oxygen 6 = 8 Valence electrons MgAl 2 - Magnesium 2 + 2 Aluminum 3 (6) = 8 Valence Electrons

8. Applying Charges  Give an example of a simple ionic compound. Label the anion and the cation.  Give an example of a complex ionic compound. Label the anion and the cation.
