Bonding in chemistry refers to the forces that hold atoms together in compounds. The main types of bonding are ionic, covalent, and metallic, each with distinct characteristics and properties.
Key Concepts
- 1Ionic bonds form between metals and non-metals through the transfer of electrons.
- 2Covalent bonds involve the sharing of electrons between non-metal atoms.
- 3Metallic bonds are characterized by a 'sea of delocalized electrons' around metal ions.
- 4Bonding affects the physical and chemical properties of substances.
- 5The strength and type of bond influence melting and boiling points, conductivity, and solubility.
Simple Explanation
Bonding is how atoms stick together to form molecules and compounds. There are three main types of bonds: ionic, where electrons are transferred; covalent, where electrons are shared; and metallic, where electrons move freely around metal atoms. The type of bond affects how substances behave, like whether they dissolve in water or conduct electricity.
