WHAT IS THE ATOMIC NUMBER OF HELLIUM

Atomic number of an atom is its number of protons. And, every element is specialized by the number of protons. For example, any atom which has 2 protons is Helium (He), and contrarily, Helium atom always has 2 protons in its nucleus. Don’t be afraid of any changes about the number of protons, if the He atom has less or more proton(s), it won’t be He anymore.

Atoms are the building blocks of matter. Atoms are composed of subatomic particles called protons, neutrons, and electrons.
