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