How do we know protons exist

WebAccording to the diagram, this helium atom contains two protons, two neutrons, and two electrons. The numbers of protons and electrons make sense: the atomic number of helium is 2 2 2 2, so any helium atom must have two protons in its nucleus (otherwise, it would be an atom of a different element!).And, because this is a neutral atom, it must contain two … WebAn atom that has more or fewer electrons in orbit than protons in its nucleus is called an ion. Once the electron from its valence shell has been transferred, the sodium atom will be missing an electron; it therefore will have a positive charge and become a sodium ion.
