Presentation transcript:

Topic: Ionic and Covalent Compounds PSSA: 3.4.7.A/S8.C.1.1

Objective: TLW compare the characteristics of ionic and covalent compounds.

MI #1: What is a compound? A compound is a pure substance made of atoms of two or more elements chemically bonded. The smallest part of a compound is a molecule.

MI #2: Ionic Compounds Ionic compounds are compounds made of oppositely charged ions. Characteristics include… - Brittleness - High melting points - High solubility - Good conductors of electricity

MI #3: Covalent Compounds Covalent compounds are compounds formed through sharing of electrons by atoms of two or more elements. Characteristics include… - Low solubility - Low melting points - Poor electrical conductivity (except for acids that ionize in solution).

So What…? Real Life Application Understanding ionic and covalent compounds allows us to understand the characteristics of many everyday household substances.
