Isotopes
Alpha Particle
A reaction that involves a change in the nucleus of an atom
Combustion Reaction
Atomic Reaction
Nuclear Reaction
Radioactive Reaction
A spontaneous process in which unstable nuclei lose energy by emitting radiation.
Radiation
Radioactive Decay
Nuclear Reaction
Radiation that is made up of (a) particles; is deflected toward a negatively charged plate when radiation from a radioactive source is directed between two electrically charged plates.
Radiation that is made up of (a) particles; is deflected toward a positively charged plate when radiation from a radioactive source is directed between two electrically charged plates
A particle with two protons and two neutrons, with a 2+ charge; is equivalent to a helium-4 nucleus and is emitted during radioactive decay
Beta particle
Alpha particle
A high speed electron with a 1- charge that is emitted during radioactive decay
Beta particle
Alpha particle
High-energy radiation that has no electrical charge and no mass, is not deflected by electric or megnetic fields, usually accompanies alpha and beta radiation, and accounts for most of the energy lost during radioactive decay.
