How is a sodium ion and a neon atom similar?
A sodium ion would have a charge on it, such as a positive charge, a cation, or a negative charge, an anion. Take your charge to be Na+1. This means that sodium is missing one electron, thus having one more proton giving it a positive charge. Na normally has 11 electrons, but this plus one knocks it down to 10. Neon at a neutral charge has 10 electrons. So, a sodium ion and neon atom have the same number of electrons (but only if the Na ion is +1 charge).
