How many protons are in a helium atom

WebThe atomic number is 17, thus the ion contains 17 protons. The mass number is 35, therefore it contains 35 – 17 = 18 neutrons. Because it is negatively charged (-1), it must have one more electron as compared to protons, thus 17 + 1 = 18 electrons. Test Yourself Determine the number of electrons in each of the following ions.
