Lewis structure of SF6

Lewis structure of `SF_6` is also known as the electron dot structure of SF6. we will discuss how to draw Lewis’s structure of Sulphur hexafluoride.

We will discuss the electron dot structure of `SF_6` through the following points

 

 

1. Formula of Sulphur hexafluoride

2. Electronic configuration of Sulphur

3. Electronic configuration of Fluorine

4. Find the central atom in the compound

5. Draw the structural formula of Sulphur hexafluoride

6. Electron dot structure of Sulphur hexafluoride

 

Formula of Sulphur hexafluoride

`SF_6`

Electronic configuration of sulphur

`1s^2 2s^2 2p^6 3s^2 3p^4`

Electronic configuration of fluorine

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

 

Find the central atom in the compound

Sulphur hexafluoride has one sulphur atom and six fluorine atoms, so sulphur is the central atom of the compound.

 

Structural formula of `SF_6`

One sulphur atom has 6 valence electrons and can share 1 electron each with six fluorine atoms.

 

Sulphur has six valence electrons and requires two electrons to complete the octet.

Fluorine has 7 valence electrons and requires one more electron to complete an octet.

Sulphur and each fluorine share one -one electron to form a covalent bond between them.

But after sharing electrons, sulphur has 12 electrons in the outermost shell.

So the number of electrons in the outermost shell of sulphur increases from 8 electrons (octet), this happens due to the ability of sulphur to expand its octet in specific compounds.
