Chemical Reactions and Equations, 21. For example, in going from the neutral Fe atom to the Fe2+ ion, the Fe atom loses its two 4s electrons first, not its 3d electrons, despite the fact that the 3d subshell is the last subshell being filled. In the p block, the number of valence electrons is equal to the group number minus ten. The third electron will go on another side of the symbol: Again, it does not matter on which sides of the symbol the electron dots are positioned.

Thus in comparing the electron configurations and electron dot diagrams for the Na atom and the Na+ ion, we note that the Na atom has a single valence electron in its Lewis diagram, while the Na+ ion has lost that one valence electron: Technically, the valence shell of the Na+ ion is now the n = 2 shell, which has eight electrons in it. We can mark these electrons and indicate what happens to them when an element reacts. 4. Why do oxygen and sulfur have the same electron dot structures? Electrons exist outside of an atom‘s nucleus and are found in principal energy levels that contain only up to a specific number of electrons. Draw the Lewis electron dot diagram for each ion. In making cations, electrons are first lost from the highest numbered shell, not necessarily the last subshell filled.
