Chemical Reaction

One can define a chemical reaction as the interaction of an element with another element resulting in the formation of a compound. A chemical reaction can be defined as the formation or breaking of an atomic bond like an ionic bond, a covalent bond, or a metallic bond.

  • The formation or breaking of a molecular bond like the Hydrogen bond or Vaan der Waal's bond produces a change in physical properties.
  • An ionic bond is formed by the transfer of a valence electron between two atoms.
  • A covalent bond is formed by the sharing of a pair of valence electrons between two atoms.
  • A metallic bond is formed when valence electrons are shared by a very large number of atoms.
