what does an atom have in common with an ion?
The Fluoride ion, neon atom, and sodium ion all have the same electron configuration and known as ISO-ELECTRONIC ions.
Both fluoride ion and sodium ion are isoelectronic with neon. That means all have 10 electrons.
neon only because sodium loses an electron an its outer shell becomes empty making its configuration the same as neon and fluorine gains an electron making its configuration the same as neon as well.
While a sodium ion and neon atom both have 10 electrons they are of different elements as a neon atom has 10 protons while sodium has 11. As a result the neon atom is neutral while the sodium ion carries a positive charge. So neon can exist on its own as a gas while sodium ion needs a negative ion to balance its charge and form an ionic solid.
They all have full outer shells. in other words 8 electrons in the outer shell

neon
Sodium is atomic number 11, while neon is atomic number 10. We would already expect sodium to be heavier, but the most common stable isotope of sodium has 12 neutrons, and the most common stable isotope of neon has only 10. Since the atomic weight can be approximated by the sum of neutrons and protons (and the number of protons is the atomic number), we can guess that sodium's atomic mass is 23 and neon's is 20.
Neon is isoelectronic with the sodium ion.
