Chemistry is the study of matter, its composition, structure, properties, and the changes it undergoes. It explores how atoms combine through chemical bonding to form elements, compounds, and mixtures, and how these interact through physical and chemical reactions. Central concepts include atomic structure, the periodic table, bonding (ionic, covalent, metallic), states of matter, energetics, kinetics, and equilibrium. Inorganic chemistry examines groups of elements and their reactions, while organic chemistry focuses on carbon-based compounds such as hydrocarbons and polymers. Analytical chemistry provides techniques to identify and quantify substances, and physical chemistry explains reactions using principles like thermodynamics and quantum theory. Overall, chemistry underpins biology, physics, medicine, engineering, and environmental science by explaining the fundamental behaviour of materials in our world.
