Chem PMP3 Radioactiv

Radioactive Reactions

Isotope any ot two or more atoms of an element that are chemically alike but have different matter.
Isotope Notation Atomic Mass on left top; Atomic No. on left bottom of Chemical symbol
Mass Number sum of neutrons and protons in the nucleus of an atom
Proton a particle with a positive electric charge equal in magnitude to that of an electron bit of an opposite sign; located nucleus
Neutron a subatomic particle of about the same mass as a proton but w/o an electric charge; located in the nucleus
Electron a stable subatomic particle with a charge of negative electricity
Ion an atom of group of combined atoms that has a charge b/c loss or gain of electrons
Anion a negatively charged ion, one that would be attracted to the anode in electrolysis
Cation a positively charged ion, one that would be attracted to the cathode in electrolysis
A atomic mass
Z atomic no.
Half-life the time taken for the radioactivity of a specified isotope to fall to half its original value
Alpha Particle a helium nucleus emitted by some radioactive decay of substances
Beta Particle a fast-moving electron emitted by some radioactive substance
Gamma Ray penetrating electromagnetic radiation of a kind arising from the radioactive decay of atomic nuclei
Decay change from an element into a different element, usually with some other particles & energy emitted
