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 … WebAtomic or ionic charge = number of protons − number of electrons. An atom that gains one or more electrons will exhibit a negative charge and is called an anion. Positively charged atoms called cations are formed when an atom loses one or more electrons. For example, a neutral sodium atom (Z = 11) has 11 electrons.
