Radioactivity : Occurs when the nucleus of an unstable atom breaks down in a process called radioactive decay
Alpha Particle : Positively charged, more massive than any other type of nuclear radiation, and made of 2 protons and 2 neutrons
Alpha Decay : Results in a new element with an atomic number less than 2 and a mass number less than 4 from the original element
Beta Particle : Fast moving negative electrons or positive positrons
Beta Decay : Will result in the atomic number increasing by 1 from the original value and the mass number staying the same
Gamma Ray : A form of electromagnetic energy
Gamma Decay : Does not change the mass number or atomic number of an atom
Transmutation : The changing of one element into another by radioactive decay, nuclear bombardment, or similar processes
Half Life : The time it takes for one half of a sample of radioactive material to decay
Decay Curve : A graph of the number of radioactive parent nuclei remaining in a sample as a function of time
Fission : The process by which a nucleus splits into two or more fragments and releases neutrons and energy
Fusion : The process in which light nuclei combine at extremely high temperatures, forming heavier nuclei and releasing energy
