Molecules are the fundamental building blocks of matter, forming the basis of everything we see, touch, and experience in the physical world. Composed of atoms bonded together, molecules can be as simple as a molecule of water (H₂O) or as complex as DNA. Understanding molecules is crucial for the fields of chemistry, biology, and physics, as they are involved in every chemical reaction and biological process. In chemistry, molecules are classified based on their composition and the types of bonds that hold them together. Covalent bonds, where atoms share electrons, form molecules like oxygen (O₂) and nitrogen (N₂). Ionic bonds, where electrons are transferred between atoms, create compounds such as sodium chloride (NaCl).
