WebThe electron dot diagram for helium, with two valence electrons, is as follows: By putting the two electrons together on the same side, we emphasize the fact that these two electrons are both in the 1ssubshell; this is the common convention we will adopt, although there will be exceptions later. WebThis means that for every electron there will be a proton, so you will be able to determine which element the atom is by comparing the electrons to the atomic number. For example, the above diagram has 2 electrons, so it is the element with atomic number 2, helium. Let’s look at an example.
