The atomic number of Helium is 2.
→Atomic number of an element is defined by the number of protons existing in the nucleus of that element. Helium has 2 neutrons in its nucleus.
→It is a noble gas, that means it does not react with any element. This property is shown by Helium because it's valence shell is complete.
