How many protons does the element helium 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] WebHelium is composed of two electrons, two protons, and usually two neutrons. It is a colorless, odorless, inert gas. Helium is a byproduct of both fusion and fission. In 1868, Helium was first detected in the sun's spectrogram. Its name is derived from the Greek word, 'helios' meaning sun. Helium atom proton electric charge diagram.
