Their electron configuration =)
They all have a full outer electron shell, making them stable. However, the fluoride ion and sodium ion are charged particles (ions) due to the gain or loss of electrons, while neon is a neutral atom because it has a complete outer electron shell naturally.
If a sodium atom loses an electron to become a Na+ ion, its electron configuration will be the same as neon (1s22s22p6). Both sodium and neon have stable electron configurations.
A sodium ion is a sodium atom that has lost an electron, giving it a positive charge. Neon, on the other hand, is a noble gas with a complete outer electron shell, making it stable and unreactive. Sodium ions are typically involved in chemical reactions, while neon atoms are inert.
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).
Sodium atom has 11 electrons...whereas sodium ion has 10 electrons. Sodium ion is more stable because it has a complete octet(noble gas configuration-Neon) which makes it inert like noble gas. Sodium atom tends to lose the extra electron which is in 3-s shell to become stable.
what does an atom have in common with an ion?
Neon is isoelectronic with the sodium ion.
The Fluoride ion, neon atom, and sodium ion all have the same electron configuration and known as ISO-ELECTRONIC ions.
They all have full outer shells. in other words 8 electrons in the outer shell
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.

An example of an ion and atom that are isoelectric is sodium ion (Na+) and neon atom (Ne). They are both isoelectric with each other because they both have 10 electrons. Sodium ion loses one electron from its neutral state to become Na+, while neon gains one electron to become Ne.
The sodium ion has one more proton than neon and 2 more neutrons. It has a positive charge where neon is neutral but they both do have 10 electrons
Fluoride, neon, and sodium ions all have closed electron shells, making them stable. Fluoride and neon have a full outer shell with eight electrons, while sodium has a stable electron configuration after losing one electron to achieve a full outer shell.
