Question

Select the correct formula for sulfur hexafluoride. f6s2 f6so3 sf6 s2f6

Answer 1

The correct formula for sulphur hexafluoride is SF6.

Answer 2

The answer would be:

$SF_{6}$

If you'd like to know why:

Sulfur is a non-metal and Flourine is a non-metal

Because they are both non-metal, we know that they would be a covalent bond.

In naming covalent bonds, you need to consider the number of atoms of each element in the compound.

Sulfur hexaflouride

Sulfur alone would indicate that there is  only 1 atom of sulfur is involved in the compound.

Hexa means 6 so hexaflouride means that there are 6 flourine atoms.

If you put it in a chemical formula, you put the number of atoms as a subscript of in front of each symbol of the atom.

$S_{1}F_{6}$

Since there is only 1 sulfur, we do not need to put the 1 anymore so you are left with:

$SF_{6}$
