Explanation:
Potassium and Sodium are both metals on the periodic table. Both elements are found on the s-block of the table. Therefore, it is not possible for both of them to combine to form a compound.
For a compound to form two elements must combine in a definite order to given single product.
The combination is facilitated by a loss, gain or sharing of electrons between two species. This leads to an attraction between the combining species.
Both Sodium and potassium would prefer to lose electrons and there is no reason for them to combine to form a compound.

Answer: AIP
There are two types of substances mixture and pure substance. Mixture has NO chemical formula and a pure substance has a chemical formula. There are two types of pure substances, elements (mono atomic and molecular) and compounds ( covalent and ionic).
Ionic compounds do not exist in independent molecular form. They form three dimensional crystal lattice, in which each ion is surrounded by oppositely charged ion. so the ratio of ion is called the formula unit
