How may protons does the helium atom have
WebHelium-2 or 2 He is an extremely unstable isotope of helium. Its nucleus, a diproton, consists of two protons with no neutrons. According to theoretical calculations, it would have been much more stable (although still undergoing β + decay to deuterium) if the strong interaction had been 2% greater. [14] WebNeutral carbon-14 contains six protons, eight neutrons, and six electrons; its mass number is 14 (six protons plus eight neutrons). These two alternate forms of carbon are isotopes. Some isotopes are stable, but …
