Chapter 18 Review

Physical Science

Alpha Particle Composition and Strength Positively charged, two protons, two neutrons, weakest of nuclear radiation, can be stopped with paper.
Beta Particle Composition and Strength Composed of one electron, stronger than alpha particle and faster, foil to block.
Gamma Ray Composition and Strength Strongest of nuclear radiation, electromagnetic waves, concrete or lead to block, and no mass or charge.
Transmutation Process of one element changing to another element through nuclear decay.
Nuclear Fusion Nuclear reaction where low mass nuclei fuse to form large mass nuclei.
Strong Force Protons and Neutrons are attracted to each other because of this force.
Radioactivity Process of nuclear decay.
Chain Reaction Ongoing series of fission reactions.
Tracer Any radioisotope that is used to detect changes in bodily functions.
Critical Mass Amount of material required for each fission reaction to produce another.
Uranium Discovered By Henri Becquerel.
Two Elements Discovered By Henri Becquerel and Marie Curie Polonium and Radium.
