WebHow many electrons does helium gain? The one electron in hydrogen, H, goes into the first electron shell, the one with the lowest possible energy. The second electron added to make the helium atom also goes into the first electron shell. This lowest electron shell can contain a maximum of only 2 electrons, so helium has a filled electron shell. WebFeb 28, 2015 · In helium's case, you have 2 protons that are in the nucleus and 2 electrons that surround the nucleus. Each proton carries a +1 charge, while each electron carries a -1 charge. If the total positive charge and the total negative charge add up to give zero, the atom is said to be neutral. In helium's case, 2 protons and 2 electrons will give
