Well, I looked at the Periodic Table, and saw that for He, Z=2. If Z=2, this means that there are 2 positive charges, 2 protons, in the helium nucleus, and for electrical neutrality there must be 2 negative charges, 2 electrons, also associated with the atom.

WebWhen we look at an atom, we find that it has the same about of protons as it does electrons. So, if we look at oxygen, we see that its atomic number is 8, meaning that it has 8 protons. We can also assume that it has 8 electrons. So, oxygen has eight positive particles plus eight negative particles. Think of this as 8+ (-8) or 8-8.
