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.
what does an atom have in common with an ion?
The sodium ion (Na+) is a cation (positive charge) and the fluoride ion (F-) is an anion (negative charge).
Fluoride ion is symbolised by F- .(Mind the spelling of flUOride, it is not flouride)
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.
Both fluoride ion and sodium ion are isoelectronic with neon. That means all have 10 electrons.

Their electron configuration =)
The sodium ion (Na+) is a cation (positive charge) and the fluoride ion (F-) is an anion (negative charge).
Fluoride is an ion of the element fluorine. So it is not a compound. However sometimes the compound sodium fluoride, a common ingredient in toothpaste, is simply referred to a fluoride.
Neon is isoelectronic with the sodium ion.
si
Na+ ion and neon are isoelectronic.
Fluoride itself is just the ion of the nonmetal fluorine. To form a substance it must be combined with a positive ion. In most cases, but not all, this positive ion is a metal. In most dental products contain sodium fluoride, sodium being a metal. Fluoride is sometimes confused with the mineral fluorite, which is calcium fluoride. Calcium is also a metal.
Fluoride itself is a monatmic ion of the element fluorine. It must be paired with a positive ion to form a compound. The fluoride in toothpaste is sodium fluoride. Some people confuse fluoride with the mineral fluorite (calcium fluoride), which is a compound.
