How many electron fluorine lost or gain?

Answer 1

Electron configuration of Florine: 1s^2 2s^2 2p^5 Electron configuration of Florine with an extra electron: 1s^2 2s^2 2p^6 An extra electron in places in the P orbital, so the exponent changes from a 5 to a 6. Note: The "^" symbol means the the following number is in the form of a superscript.

Answer 2

1s2, 2s2 2p5 or [He]2s2 2p5

Like all halogens, it has a valence of -1 requiring one electron to obtain a stable noble gas configuration.

Fluorine is one of the diatomic elements, so it appears as an F2 molecule.
1s22s22p5

Answer 3

Fluorine only needs to gain one electron to complete its octet. Check out the Periodic Table, the column furthest to your right is happy with all 8 electrons. fluorine is in the row next to it so it is missing one for a complete octet. Go over another row and look at Oxygen. Oxygen wants two electrons to complete its octet.

Answer 4

This is a chemical element. You can find the how many electron in a single atom by using a periodic table.

Answer 5

Fluorine is a non metal element. There are 9 electrons in a single atom.

Answer 6

Fluorine has seven valance electrons and needs eight to have a full outer shell, so it will gain one electron when it forms a compound with a metal, giving it a charge of 1-

Answer 7

Fluorine has an atomic number of 9, so it has 9 electrons. To become a more stable element it gains an electron to have a full outershell (2, 8 = 10). This gives fluorine a charge of 1-.

Answer 8

Yes, Fluorine tends to want to gain electrons to achieve a stable octet with the Neon electron structure.

Answer 9

To become a noble gas, 1.

Answer 10

Fluorine gain one electron.
