Radioactive+Decay+Notes

Radioactive Decay 1 Alpha Decay: 2 Beta Decay: 3 Gamma Decay:
 * Release of alpha particles
 * consists of two protons and two neutrons same as a helium nuclei
 * is positively charged due to the protons
 * decreases atomic number by 2 and atomic mass by 4
 * Releases electrons
 * Caused by too many neutrons
 * A neutron changes into a proton and an electron
 * The negatively charged electron leaves the positively charged nucleus.
 * Atomic number increase by 1 but mass stays the same
 * Beta particles are electrons.
 * Releases Gamma radiation
 * Consist of high-energy electromagnetic waves
 * Similar to X-rays
 * Almost always accompanies alpha and beta decay
 * No charge, no change in atomic number or atomic mass
