We’re being asked to determine the number of valence electrons in Ne2+ ion.
Before we can do that, we have to first write the electron configuration of a neutral ground state neon.
You can determine the ground-state electron configuration of Neon (Ne) by locating the position of Ne in the periodic table.
Ground-state means that the element is in its lowest energy form (not in excited state). Neutral neon means it has no charge, meaning no electrons are removed or added in the atom.
You will see in the above illustration of the periodic table that Ne is in Period 2, Group 8A, and p-block (noble gas group).
How many valence electrons are in Ne2+?
