ATOMIC ENERGY
By. Sam Irish
Nuclear Radiation
High energy particles and rays that are emitted by the nuclei of some atoms; alpha particles, beta particles, and gamma rays are types of nuclear radiation
Isotopes
Atoms that have the same number of protons but have different numbers of nuetrons
Half-Life
The amount of time it takes for one-half of the nuclei of a radioactive isotope to decay
Beta Decay
The release of a beta particle from a nucleus
Radioactivity
Gamma Decay
The ability of some elements to give off nuclear radiation
The release of gamma rays from a nucleus
Nuclear Fission
Radioactive Decay
The process in which a large nucleus splits into two smaller nuclei with the release of energy
The process in which the nucleus of a radioactive atom releases nuclear radiation
Mass Number
Nuclear Fusion
The sum of the protons and nuetrons in an atom
Two or more nuclei with small masses join together, or fuse, to form a larger, more massive nucleus
Nuclear Chain Reaction
Alpha Decay
A continuous series of nuclear fission reactions .
The release of an alpha particle from the nucleus
