Particles & Structure Atom, Molecule, Ion: Basic units of matter. Electron, Proton, Neutron: Subatomic particles. Nucleus: Atom's center. Orbital, Energy Level: Electron locations/energies. States & Mixtures Solid, Liquid, Gas: States of matter. Solution, Solvent, Solute: Dissolved substances. Alloy, Mixture, Emulsion: Combinations of substances. Properties & Behaviors Density: Mass per unit volume. Malleable, Ductile: Shapeable. Conductive: Conducts electricity/heat. Reactive, Inert, Stable: Tendency to react. Exothermic, Endothermic: Releases/absorbs heat. Acid, Base, pH: Acidity/basicity. Reactions & Processes Synthesis (Combination), Decomposition, Displacement: Types of reactions. Oxidation/Reduction (Redox): Electron transfer. Catalysis, Inhibition: Speeds up/slows down reactions. Distillation, Sublimation, Crystallization: Phase changes/separations. Equilibrium: Reversible reaction balance. Terms for Bonding & Types Covalent, Ionic, Metallic Bonds: Types of connections. Polymer, Monomer: Large chain/building block.
