Fluorine's atomic number is 9. Thus, neutral fluorine has 9 protons and 9 electrons. It's total configuration then is 1s2 2s2 2p5, so its valence configuration is 2s2 2p5.
[He].2s2.2p5
Fluorine is normally: 1s22s22p5 But with the addition of an electron to make F-, the answer is: 1s22s22p6
1s^2 2s^2 2p^5 Note: The "^" symbol means the the following number is in the form of a superscript.
[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].
It accepts one electron.
this is because a fluorine ion is one electron short of a full valence shell,which makes getting another electron to fill the shell very favourable,filling the shell makes the molecule much more stable
The electron configuration for an atom of fluorine is [He]2s2.2p5.
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.
The electron configuration of mendelevium is [Rn]5f13.7s2.
The electron configuration for an atom of fluorine is [He]2s2.2p5.

The condensed electron configuration of polonium is [Xe] 6s^2 4f^14 5d^10 6p^4.
1s2,2s2,2p5
The answer is carbon

Fluorine has the electron configuration: 1s22s22p5, sometimes written as [He]2s22p5
The "Noble gas electron configuration," or the condensed electron configuration, for F is [He] 2s2 3p5.
Fluorine is normally: 1s22s22p5 But with the addition of an electron to make F-, the answer is: 1s22s22p6
