What are the six properties of ionic compounds? Properties Shared by Ionic Compounds They form crystals. They have high melting points and high boiling points. They have higher enthalpies of fusion and vaporization than molecular compounds. They’re hard and brittle. They conduct electricity when they are dissolved in water. They’re good insulators. Why are covalent […]

Why is solid liquid and gas important? Solids, liquids and gases are three states of matter. It is important to understand the particle nature of matter. The particles that make up matter are not ‘small bits of solid’ or ‘small drops of liquid’ but atoms and molecules. The physical characteristics of those atoms and molecules […]
