Potassium fluoride (KF) consists of potassium (K) and fluoride (F) ions. Potassium, being in the first group of the periodic table, typically forms a +1 charge, while fluoride, being in the halogen group, forms a -1 charge. The correct picture would show a 1:1 ratio of potassium to fluoride ions, indicating a simple ionic compound with a balanced charge.
