Acids are substances that release hydrogen ions (H⁺) in solution, bases release hydroxide ions (OH⁻) or accept H⁺, and salts are formed from the neutralization reaction between an acid and a base. They play a key role in chemical reactions, pH regulation, and many biological and industrial processes.

The mole is a fundamental unit in chemistry that represents 6.022 × 10²³ particles (Avogadro's number) of a substance—be it atoms, molecules, or ions. It links the microscopic world of atoms to the macroscopic world we can measure, allowing chemists to relate mass to number of particles in chemical reactions.

States of Matter & Kinetic Theory explores the physical forms of matter solid, liquid, and gas based on particle arrangement and movement. The Kinetic Theory explains that particles are in constant motion, and this motion increases with temperature. Changes in state (melting, boiling, etc.) occur when particles gain or lose energy. The theory also underpins the gas laws, describing how gases respond to pressure, volume, and temperature changes.

Chemical bonding explains how atoms combine to form compounds by gaining, losing, or sharing electrons. The main types are ionic bonds (between metals and non-metals through electron transfer), covalent bonds (between non-metals through electron sharing), and metallic bonds (between metal atoms with delocalized electrons). These bonds determine the physical and chemical properties of substances and the shapes of molecules.
