How many protons are there
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, so any helium atom must have two protons in its nucleus (otherwise, it would be an atom of a different element!). WebThe atomic number of an element is equal to the number of protons and electrons in that element. Therefore, a gold atom has seventy-nine protons and seventy-nine electrons. The number of neutrons in an atom can be determined by the difference between the atomic mass and the number of protons.
