Beryllium-8，is one of Beryllium's isotope, it has 4 neutrons and 4 protons,it has four electrons when its oxidation state is 0,it is one of the Radionuclides.
Form
[edit]In a nuclear fusion, if two Helium-4 collides, it will become a Beryllium-8, but it will soon decay and be two Helium-4 again, but if it collides with another Helium-4, it will become a Carbon-12, it is called Triple-alpha process.[1]
Theory
[edit]George Gamow in his Big Bang theory, discovered that the isotopes have decayed to fast that nuclear fusion can't keep going on, and it will end very fast, and that only can develop Hydrogen, Helium and Lithium, but it can't develop the elements which have a higher mass.[2]But, Fred Hoyle believes that the elements which have a higher mass is developed during the Triple-alpha process and when the stars exploded.[3]
