Unstable atomic nuclei will spontaneously decompose to form nuclei with higher stability. The energy and particles which are released during the decomposition process are called radiation.When unstable nuclei decompose in nature, the process is referred to as natural radioactivity.When a beta particle is ejected, a neutron in the nucleus is converted to a proton, so the mass number of the nucleus is unchanged, but the atomic number increases by one unit.For example: Gamma rays are high-energy photons with a very short wavelength (0.0005 to 0.1 nm).It consists of a nucleus of two protons and neutrons, and two electrons in atomic orbits.The most common form is Helium-4, which is believed to be the product of Big Bang nucleosynthesis. This event is believed to have produced the majority of helium-4, along with small amounts of the hydrogen, helium and lithium isotopes.
He noticed the diamond combined with oxygen to form carbon dioxide which led him to conclude that diamond and charcoal were both made from carbon.This is due in part to its very high nuclear binding energy, plus the fact that is produced by both nuclear fusion and radioactive decay.And yet, scientists have only been aware of its existence since the late 19th century.When an alpha particle is ejected from a nucleus, the mass number of the nucleus decreases by four units and the atomic number decreases by two units.For example: Beta radiation is a stream of electrons, called beta particles.
