What Are Chemical Bonds?

Overview of Chemical Bonds

  • Chemical bonds are the attractive forces that hold atoms together in a compound. There are two main types: ionic and covalent bonds.

Ionic Bonds

  • An ionic bond occurs when one atom donates or transfers electrons to another atom, resulting in the formation of charged ions.
  • The atom that loses electrons becomes positively charged, while the atom that gains electrons becomes negatively charged.
  • The attraction between these oppositely charged ions forms the ionic bond. For example, chloride ion (Cl-) attracts sodium ion (Na+) to create sodium chloride (table salt).

Covalent Bonds

  • Covalent bonds form when atoms share their electrons instead of transferring them completely.
  • A simple example is water (H2O), where each hydrogen atom shares its electron with oxygen.
