sodium's atomic number is 11 and since protons and electrons are the same number as the atomic number, there are 11 protons and 11 electrons, to get the neutrons you take the isotope of sodium you are given, in this case 23 and subtact the number of protons, so 23-11=12. Therefore there are 12 electrons.
