Hydrogen is the first element on the periodic table, with an atomic number of 1. The one means that it has 1 proton, and the number of protons and electrons is the same, so it has 1 electron too. WebExplanation: Helium is located in period 1, group 18 of the Periodic Table and has an atomic number equal to 2. As a result, neutral helium will only have 2 electrons surrounding its nucleus. Valence electrons are the electrons located in an atom's outermost shell. In helium's case, both its electrons will be valence electrons. biotonic sort
