Naming Ionic Compounds Chemistry GLE: Physical Science PS 5 - Write and name formulas for ionic and covalent compounds. (PS-H-A2) PS 9 - Draw accurate valence electron configurations and Lewis dot structures for selected molecules, ionic and covalent compounds, and chemical equations. (PS-H-B1)

Science as Inquiry SI5 - Utilize mathematics, organizational tools, and graphing skills to solve problems (SI-H-A3) SI9 - Write and defend a conclusion based on logical analysis of experimental data (SI-H-A6) (SI-H-A2)

Cation + Anion = Net Charge of Zero (+) + (-) = 0 All Ionic Compounds (Formula units) have a net charge of zero.

Names for Ions and Ionic Compounds (cont.) Section 7-3

Names for Ions and Ionic Compounds (cont.) Chemical nomenclature is a systematic way of naming compounds. Name the cation followed by the anion. For monatomic, cations use the element name. For monatomic anions, use the root element name and the suffix –ide. To distinguish between different oxidation states of the same element, the oxidation state is written in parentheses after the name of the cation. When the compound contains a polyatomic ion, name the cation followed by the name of the polyatomic ion. Section 7-3
