Chemistry: The Central Science
Chemistry bridges physics and biology — explaining how atoms combine to form the molecules of life, materials, and medicine. Chemistry vocabulary is essential for understanding reactions, bonding, the periodic table, and the molecular basis of biological processes.
Topics Covered
Atomic Structure
Protons, neutrons, electrons, isotopes, and atomic number.
Chemical Bonding
Ionic bonds, covalent bonds, and polar molecules.
Reactions and Laws
Conservation of mass, acid-base reactions, and oxidation.
Periodic Table
Element organization, groups, periods, and properties.
