Question

How do the electron configuration of fluorine, fluoride ion, and neon compare?

Answer 1

The electron configurations of fluoride and neon are the same while fluorine has one less electron.

Explanation:

Fluorine F has the electron configuration of

`1s^2 2s^2 2p^5`

This configuration is unstable lacking one electron to achieve a filled electron shell.

Fluoride `F^-1` has the electron configuration of

`1s^2 2s^2 2p^6`

This configuration is stable but leaves Fluoride with a negative one charge which causes it to be reactive chemically.

Neon Ne has the electron configuration of

`1s^2 2s^2 2p^6`

This configuration is stable as it is a filled electron shell. Neon also has a charge of zero as Neon has 10 electrons and 10 protons.

Fluoride `F^-1` and Neon have the same electron configuration but different charges.
Florine has a different electron configuration with one less electron.
