| Term | Definition |
|---|---|
| Solute | A substance who's particles are dissolved in a solution |
| Solvent | The substance in which the solute dissolves |
| dissociation | the process in which an ionic compound separates into ions as it dissolves. |
| dispersion | breaks into smaller pieces as it dissolves. |
| ionization | the process in which neutral molecules gain or lose electrons |
| acid | an acid that produces hydronium ions |
| indicator | an substance that changes color in an acid or base |
| base | a compound that produces hydroxide ions |
| neutralization | the reaction between an acid and a base |
| salt | what is created after neutralization |
| pH | a solutions measure of its hydronium ion consentration |
| buffer | a solution that is resistant to large changes in pH |
| electroyle | a substance that ionizes or dissociates into ions when it is turned into water |
| radioactivity | a process in which an unstable atomic nucleus emits charged particles |
| radioisotope | an atom containing an unstable nucleus |
| nuclear radiation | charged particles and energy that are emitted from the nuclei of radioisotopes |
| alpha particle | a positively charged particle made up from two protons and neutrons |
| beta particle | an electron emitted by an unstable nucleus |
| gamma ray | a penetrated ray of energy emitted by an unstable nucleus |
| background radiation | nuclear radiation that occurs naturally in the environment |
| strong nuclear force | is the attractive force that binds protons and neutrons together in the nucleus |
| fission | is a splitting of an atomic nucleus into two smaller parts |
| chain reaction | neutrons released during the splitting of an initial nucleus trigger a series of nuclear fissions |
| critical mass | the smallest possible mass of a fissionable material that can sustain a chain reaction |
| fusion | a process in which the nuclei of two atoms combine to form a larger nucleus |
| plasma | state of atoms in which they are stripped of their electrons |
