1 Lecture 06 Chemical Compounds Ions and Ionic Compounds 3.5 Naming Ions and Ionic Compounds 3.6 Properties of Ionic Compounds 3.7 Lecture 06, Knowledge and Skills • Know types of ions • Predict the most likely charges of atomic ions • How do ions organize in solids? • Which forces hold ions together in solids? • Know common polyatomic ions and the corresponding neutral compounds, e.g., ammonia, water, acids. • Write the formulas of ionic compounds • Name atomic ions • Know the names of polyatomic ions • Name ionic compounds • Know basic properties of ionic compounds that derive from their ionic nature Ions All bulk matter is electrically neutral Consists of neutral entities or charged entities (always equal numbers of opposite charges) Monoatomic ions Individual atoms may gain or loose electrons Polyatomic ions Polyatomic ions Molecular assemblies of atoms, including polymers and extended structures, may be neutral or charged (neutral molecules or molecular ions) Positively charged ions Cations Negatively charged ions Anions Rare Gas Electron Configuration - Formation of Ions He H H Li Li + + e e Note: relative sizes! Formation of Ionic Compounds 2 Li + H 2 2 LiH The compound is stabilized by the electrostatic attractions between the cations and anions.
