Compound

A compound is a substance made from the combination of two or more elements and held together by chemical bonds that are difficult to break. The bonds form as a result of sharing or exchanging electrons between atoms.

  • A compound (chemical compound) is formed when different elements react, forming bonds between their atoms.
  • A molecule is the smallest indivisible unit of a compound that retains its chemical properties.
  • Different elements react and form bonds between their atoms to create a compound.
  • Compounds have unique properties that are different from the properties of their constituent elements.
  • Introducing a new element to a compound can lead to additional reactions and the formation of new compounds.
  • Compounds can be categorized into four types based on the type of bonding between constituent atoms:
    • Compounds held together by covalent bonds form molecules.
    • Ionic compounds are formed by the attraction between positively and negatively charged ions.
    • Intermetallic compounds are held together by metallic bonding between metal atoms.
    • Complexes are formed through coordinate covalent bonds between a central atom and ligands.
  • Compounds are one type of substance encountered in chemistry. Other types of substances include:
    • Mixtures: A substance consisting of two or more different substances that are physically combined.
    • Solutions: A homogeneous mixture where one or more substances (solutes) are dissolved in another substance (solvent).
    • Alloys: A homogeneous mixture of two or more metals, or a metal with a non-metal.
    • Colloids: A mixture where particles of one substance are dispersed throughout another substance but do not settle out or dissolve.
    • Isotopes: Different forms of an element with the same number of protons but different numbers of neutrons in their nuclei.
