Sodium fluoride has electron and ionic elements. This is taught in science.
With it being a dipositive ion, the original element has lost 2 electrons. Making the configuration 1s2 2s2 2p6 3s2 2p4. That Configuration is Sulfur.
neon!
A neutral sodium must lose one electron in order for the resulting sodium ion to have the same electron configuration as an atom of the element neon.
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.
The electronic configuration of sodium is [Ne]3s1. Sodium has one valence electron. And it belongs to group 1. The valence electron is in 3s orbitals and it tells that sodium is a s-block element and is in period 3.

In NaF, there exists Na+ and F- ions and with the electron configuration of [He]2s22p6 (for Na+) and [He]2s22p6 (for F-)
The Fluoride ion, neon atom, and sodium ion all have the same electron configuration and known as ISO-ELECTRONIC ions.
A neutral sodium must lose one electron in order for the resulting sodium ion to have the same electron configuration as an atom of the element neon.
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.
Atoms of the element sodium (atomic number 11) have the electron configuration 1s22s22p63s1 with the noble gas form [Ne] 3s1

An iron atom is a different element than a sodium atom because it has a different ground state electron configuration. In fact, any atom that differs from any other atom in ground state electron configuration is a different element.
