Constituents of different elements, except for noble gases, do not have a complete octet of electrons, prompting them to combine with other atoms through chemical bonds to achieve stability. This process is called chemical bonding and is determined by the valency of the atoms.
An ion is an electrically charged species. Positively charged ions are called cations, while negatively charged ions are called anions. Cations have fewer electrons than their corresponding atoms (e.g., Na+, H+, Mg2+), while anions have more electrons (e.g., F−, Cl−, O2−).
Chemical bonds are classified based on the mode of electron transfer or sharing and the forces of attraction involved:
Electrovalent or Ionic Bond
Covalent Bond
Coordinate or Dative Covalent Bond
