Mr. Beatty's Vocab HW. This is my FUN(erd) way of studying!

Alpha Particles A particle with two protons and two neutrons, with a 2+ charge. Equivalent to Helium -4 nucleus. Represented by (Insert fish-like "a" here)
amu Atomic Mass Unit- 1/12 of the mass of an atom.
Atomic Mass The weighted average mass of the isotopes of a given element.
Mass Number # after an element's name; sum of protons and neutrons
Atomic Number # of protons in an atom.
Proton + Charged Particle in an atom (Duh)
Electron - Charged Particle in an atom (Duh)
Beta Particles A high speed electron with a 1-charge that is emitted during radioactive decay.
Gamma Radiation Has no mass or electrical charge; is not deflected by electric or magnetic fields. Accompanies alpha and beta radiation.
Neutrons Neutral Charged Particle
Isotopes Atoms of the same element with different # of neutrons
Nucleus Extremely small center of an atom. Composes of protons, neutrons, and electrons. Positively charged.
Nuclear Equation Type of equation that shows the atomic # and mass number of the particles involved.
Radioactive Decay Spontaneous process in which unstable nuclei lose energy by emitting radiation.
Radioactivity The process in which some substances spontaneously emit radiation.
