Give the structure of sulphur tetrafluoride .

Explanation

To determine the structure of sulfur tetrafluoride (SF4), we can follow these steps:

### Step 1: Determine the Valence Electrons
- Sulfur (S) has 6 valence electrons.
- Each fluorine (F) atom has 7 valence electrons, but since it forms a bond by donating 1 electron, we consider only 1 electron from each fluorine for bonding.
- With 4 fluorine atoms, the total contribution from fluorine is 4 electrons.

**Total valence electrons = Valence electrons of S + Valence electrons from F**
