Compounds are made up of only one type of Molecule that are composed of two or more Elements and can be separated into simpler substances and elements by chemical methods only.
- Ionic — Components are a pair of Anions group and a Cations group. Electrons are transferred from the Cations to the Anions, usually formed when Metals react to Non-metals. E.g. NaCl
- Covalent — Components are both Anions. Electrons are shared within the bond, formed when two Non-metals react with each other. E.g. CO2
- Metallic — Components are both Metals. Electrons are stored in a “sea of electrons.” E.g. AgNO2
