Given :

A chemical compound KF_2 .

To Find :

Fix the formula for KF_2 and write the full correct formula.

So, the chemical formula KF_2 is wrong because no element has filled electron.

Therefore, to stabilise the molecule, 1 Potassium atom should make a bond from 1 Fluorine i.e KF ( correct formula ) .

Hence, this is the required solution.
