Ionic Compound

Content What is ionic compound? Properties Uses of ionic compounds Group members

What is ionic compound? a chemical compound in which ions are held together in a lattice structure by ionic bonds the positively charged portion consists of metal cations and the negatively charged portion is an anion or polyatomic ion Also called ionic compounds

Properties High melting point High boiling point High hardness Very brittle

Properties Good electrical conductivity when molten or in aqueous solution Conduct electricity when dissolve in water Are solids at room temperature

Uses of ionic compounds Table salt (form large crystals )(sodium chloride) A kind of evaporation plating material for thin film (magnesium fluoride) Fertilizers(Potassium nitrate)
