K2F
KF-
KF2
KF

Answer 1

KF

Step-by-step explanation:

• Chemical formula is a formula of a compound that shows the elements making up the compound.
• It also shows the number of atoms of each element making up the compound.

In this case;

• To know the chemical formula of potassium fluoride we need to;
• Identify the elements present and their symbols; Potassium-K and Fluoride-F
• Then identify the valency of each element; K¹ and F¹
• Then the two elements exchange the valencies and written as subscripts
• That is; K₁F₁
• The chemical formula is therefore, KF
