What kind of structure does your substance have?

You can work out the chemical structure of a substance by looking at its physical properties.

If it is a gas, liquid or a soft solid with a low melting point, then it is a simple covalent substance.

If it is a solid with a high melting point then it has a giant structure, and is either an ionic, covalent or metallic compound.

Solids with a high melting point it can either be ionic covalent or metallic

If the substance dissolves in water (without a reaction), it is probably ionic.
