5. Physical Properties Ionic Compounds States (at room temperature) Solid Electrical conductivity Solid: No Liquid: Yes Aqueous: Yes (if soluble) Boiling point and Melting Point High Solubility in water Often high Thermal conductivity Low
9. Physical properties Covalent compounds States (at room temperature) Solid, liquid, gas Electrical conductivity Usually none Boiling point and Melting point Varies, but usually lower than ionic compounds Solubility in water Varies, but usually lower than ionic compounds Thermal conductivity Usually low
