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.
