Helium number of protons in one atom

WebHelium is a chemical element. Its official symbol is He, and its atomic number is 2, which means it has two protons in its nucleus. Helium was named after Helios – the Greek Titan of the Sun – because it was first observed when analysing sunlight during a solar eclipse in 1868. Noble gases Helium is one of the seven elements known as noble gases.
