Fluorine is normally: 1s22s22p5 But with the addition of an electron to make F-, the answer is: 1s22s22p6
Fluorine, (2.7) is its electron configuration, as it has an atomic number of 9 and 9 electrons
fluoride
1s2 2s2 2p6 is the electron configuration of the fluoride ion. It has a complete octet and is isoelectronic with neon. Before it becomes an ion, it is 1s2 2s2 2p5 Then it gains an electron and has a negative charge.
EF4
The Fluoride ion, neon atom, and sodium ion all have the same electron configuration and known as ISO-ELECTRONIC ions.
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.
Fluorine's electron configuration is 1s2 2s2 2p5, and since fluoride is just fluorine with an extra electron, or F-1, its electron configuration is 1s2 2s2 2p6.

[He] 2s2 2p6
Sodium fluoride has electron and ionic elements. This is taught in science.
1s2 2s2 2p6 is the electron configuration of the fluoride ion. It has a complete octet and is isoelectronic with neon. Before it becomes an ion, it is 1s2 2s2 2p5 Then it gains an electron and has a negative charge.
In NaF, there exists Na+ and F- ions and with the electron configuration of [He]2s22p6 (for Na+) and [He]2s22p6 (for F-)
1s^22s^22p^6
[He] 2s2 3p5 is the electronic configuration of a neutral Fluorine atom.It's -1 ion (F-, fluoride ion), however is: [He] 2s2 3p6, or [Ne]
EF4
The Fluoride ion, neon atom, and sodium ion all have the same electron configuration and known as ISO-ELECTRONIC ions.
Fluorine has the electron configuration: 1s22s22p5, sometimes written as [He]2s22p5
Neon has the same electron configuration as the Fluoride ion however a spectrum of these although the same will be shifted in wave-length due to the additional charge on the Neon atoms nucelus.
