Radioactivity is the process by which unstable atomic nuclei lose energy by emitting radiation. This can include alpha particles, beta particles, and gamma rays.
5 Must Know Facts For Your Next Test
Radioactive decay occurs spontaneously and results in the transmutation of elements.
The three main types of radioactive decay are alpha decay, beta decay, and gamma decay.
Alpha particles consist of two protons and two neutrons; they have a +2 charge and are relatively heavy.
Beta decay involves the emission of an electron or positron; beta particles are lighter than alpha particles but more penetrating.
Gamma rays are high-energy photons with no mass or charge, making them highly penetrating and dangerous.
