Hi there to answer this question: let’s start off for a moment talking about an ionic compound, an ionic compound is composed of a cat ion, which is a positive ion and an an ion which is a negative ion. The cat, ions and anions can be monoatomicmeaning. Ions formed from a single atom or they can be polyatomic and a polyatomic ion refers to 2 or more non metals that are covalently bondedand as a unit. They have a charge, they have gained or lost electrons. Okay. So with this in mind, we are ready to answer this question. Question first wants us to write an example of a potassium compound that contains both ionic and covalent bonds. So that’s going to mean potassium plus a polyotomic, an ion, and i know i need an anion because potassium is a metal, so metals form cations. So potassium is going to be our positive ion and the polyatomic an ion is going to be our negative ion. All right, so, let’s write 1 of these, so potassium is k. It just has 1 valence electrons, so it forms an ion with a single positive charge. I’M going to go ahead and put this with nitrate n o 3 is the polyatomic nitrate as…
