How many protons do helium have

WebIn helium’s case, you have 2 protons that are in the nucleus and 2 electrons that surround the nucleus. Therefore, the helium atom is neutral. A helium atom has no charge, which means it has an oxidation number of 0. Neutrons have no charge. What charge is a proton? Protons are found in the nucleus of the atom. 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.
