What are the Types of Pure Substances?
A pure substance is a chemical element that is made up of only one type of atom. Pure substances are composed of elements that are chemically identical, meaning that they have the same atomic structure. These elements are highly pure and do not react with other elements to form new compounds.
Examples of pure substances include:
Metals: Metals are elements that are shiny, malleable, and ductile. For example, iron, copper, and aluminum are all metals.
Non-metals: Non-metals are elements that are dull, brittle, and not easily malleable. For example, carbon, hydrogen, nitrogen, and oxygen are all non-metals.
Ions: Ions are atoms or molecules that have lost or gained electrons. For example, sodium, potassium, and chloride ions are all ions.
Molecules: Molecules are larger than atoms and contain two or more atoms bound together. For example, water (H2O) is a molecule, and glucose (C6H12O6) is a molecule.
Pure substances are an important part of the natural world and are used in a variety of industrial applications. For example, metals are used in construction, transportation, and electrical equipment. Non-metals are used in food, medicine, and plastics. Ions are used in batteries and other devices. Molecules are used in a wide variety of products, including cosmetics, detergents, and pharmaceuticals
