This lesson covers the three main types of strong chemical bonding — ionic, covalent, and metallic — as well as intermolecular forces, the shapes of molecules, electronegativity, bond polarity, sigma and pi bonds, and modern forms of carbon. Understanding bonding and structure allows you to explain the physical properties of a wide range of substances and is examined in detail across all A-Level Chemistry specifications.
Key Definition: Ionic bonding is the strong electrostatic attraction between oppositely charged ions in an ionic lattice.
Ionic bonding involves the transfer of electrons from a metal atom to a non-metal atom, forming oppositely charged ions that are held together by strong electrostatic attractions. The resulting structure is a giant ionic lattice.
