You're asking about the number of potassium (K) and oxygen (O) atoms in a binary compound formed from these two elements. To figure this out, we need to know the specific compound's chemical formula.

Here's why:

* Binary Compounds: These are compounds made of only two elements.

* Chemical Formula: The formula tells us the exact ratio of atoms of each element in the compound.

Example:

* Potassium Oxide: Its chemical formula is K₂O. This means there are 2 potassium atoms and 1 oxygen atom in each molecule of potassium oxide.

To answer your question accurately, please provide the chemical formula of the binary compound you're interested in.
