WebThe number of nucleons is always very close to the atomic weight of the atom (which is 15.9994 for Oxygen). Here a simple way to remember this: Since an atom is electrically neutral, an atom has always the same number of electrons (negative charge) and protons (positive charge). The neutrons, of course, are neutral. 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 …
