The substances NaF and CaO are isoelectronic (have the same number of valence electrons). (b) What are the charges of each of the anions in each compound?

Video transcript

Hey everyone. Our question here is asking us to determine the charges of the ions in the ISO electronic substances. Our first one being magnesium sulfide and the second one being potassium chloride. For our first one magnesium sulfide, we know that we have magnesium with a plus two charge and sulfur with a minus two charge. Since it's in our group +68 and are an ion in this case is going to be sulfur and magnesium is going to be our caddy on. Moving on to potassium chloride. We know that potassium has a plus one charge since it's in our group one a And Chlorine is in our group seven a with a -1 charge. Again, chlorine is are an ion since it has that negative charge And the charge is going to be a -1. So I hope this made sense. And let us know if you have any questions.
