| Term | Definition |
|---|---|
| Solute | A substance whose particles are dissolved in a solution |
| Solvent | A substance in which a solute dissolves |
| Dissociation | The separation of ions in an ionic compound as the compound dissolves |
| Dispersion | The process of dissolving by breaking into smaller pieces, the process in which white light separates into colors |
| Ionization | The process by which neutral molecules gain or lose electrons |
| Acid | A compound that produces hydronium ions when dissolved in water; a proton donor |
| Indicator | A substance that changes color in the presence of an acid or shape |
| Base | A compound that produces hydroxide ions when dissolved in water; a proton acceptor |
| Neutralization | A chemical reaction between an acid and a base |
| Salt | An ionic compound formed when an acid reacts with a base |
| pH | A measure of the hydronium ion concentration of a solution |
| Buffer | A solution that is resistant to large changes in pH |
| Electrolyte | A compound that produces ions when it dissolves |
| Radioactivity | The process in which an unstable atomic nucleus emits charged particles and energy |
| Radioisotope | An isotope with an unstable nucleus |
| Nuclear Radiation | Charged particles and electromagnetic waves that are emitted from the nuclei of radioisotope |
| Alpha Particle | A positively charged particle, emitted by certain radioactive nuclei, made up of two protons and two neutrons; a helium nucleus |
| Beta Particle | An electron emitted by an unstable nucleus |
| Gamma Ray | A penetrating form of radiation emitted by an unstable nucleus |
| Background Radiation | Nuclear radiation that occurs naturally in the environment |
| Strong Nuclear Force | The powerful attractive force that binds protons and neutrons together in the nucleus |
| Fission | A nuclear reaction in which an atomic nucleus is split into two smaller parts |
| Chain Reaction | A series of fission reactions triggered by neutrons released during the fission of a nucleus |
| Critical Mass | The smallest possible mass of a fissionable material that can sustain a chain reaction |
| Fusion | A nuclear reaction in which the nuclei of to atoms combine to form a larger nucleus |
| Plasma | A state of matter in which atoms have been stripped of their electrons |
