* High melting point and boiling point: Ionic compounds typically have high melting points and boiling points because of the strong electrostatic forces between the positive and negative ions.
* Solubility in water: Ionic compounds are typically soluble in water because the water molecules can solvate the ions, breaking up the ionic lattice.
* Electrical conductivity: Ionic compounds are typically good conductors of electricity in the molten state or when dissolved in water, because the ions can move freely and carry the electric current.
* Crystal structure: Ionic compounds typically have a regular, ordered crystal structure because of the strong electrostatic forces between the positive and negative ions.
* Chemical reactivity: Ionic compounds are typically reactive with other compounds, especially those that can form covalent bonds. This is because the ionic bonds in an ionic compound are polar, meaning that they have a positive and negative end. This polarity can attract other molecules and cause them to react with the ionic compound.
If a compound has all of these properties, it is likely that it contains ionic bonds.
