Interatomic bonds are the forces that hold atoms together to form molecules or solids. These bonds arise from the interaction between the electrons of one atom and the nucleus of another atom.

There are three main types of interatomic bonds:

1. Ionic Bonds: These bonds occur between a metal and a non-metal. In an ionic bond, one atom completely transfers one or more electrons to another atom, resulting in the formation of ions with opposite charges. These ions are held together by electrostatic attraction. For example, in sodium chloride (NaCl), sodium donates an electron to chlorine, resulting in the formation of Na+ and Cl- ions, which are held together by ionic bonds.

2. Covalent Bonds: These bonds occur between non-metal atoms. In a covalent bond, atoms share electrons in order to achieve a more stable electron configuration. This shared pair of electrons creates a bond between the atoms. For example, in water (H2O), oxygen and hydrogen atoms share electrons, resulting in the formation of covalent bonds.

3. Metallic Bonds: These bonds occur between metal atoms. In a metallic bond, the valence electrons of metal atoms are delocalized and move freely throughout the crystal lattice. This creates a "sea" of electrons that hold the metal atoms together. Metallic bonds are responsible for the unique properties of metals, such as high electrical and thermal conductivity, malleability, and ductility.

These interatomic bonds determine the physical and chemical properties of substances. The strength and nature of the bond govern factors like melting and boiling points, hardness, solubility, and reactivity. Understanding these bonds is crucial in many fields, including chemistry, physics, materials science, and engineering.
