Hey, everyone. Let's take a look at this question together. The following are examples of ionic compounds except which is it. Answer choice. A sodium chloride. Answer choice B magnesium oxide, answer choice C potassium iodide or answer choice D carbon dioxide. Let's work this problem out together to try to figure out which of the following answer, choices is not an ionic compound. So in order to solve this question, we have to recall what an ionic compound is to determine which of the following is not an ionic compound. And we also have to recall the composition of each of the following answer choices. Starting off with answer choice A we have sodium chloride which we know that sodium chloride is formed by the combination of sodium which has a positive charge and chlorine which has a negative charge. So answer choice A is incorrect since it is an ionic compound. Next, we have answer choice B magnesium oxide, which we know that magnesium oxide is formed by the combination of a magnesium ion which has a two plus charge and an oxygen ion which has a two minus charge resulting in the formation of an ionic compound. So answer choice B is also correct. Next, we have answer choice C which says potassium iodide, which is formed by the combination of a potassium ion which has a positive charge and an iodine ion which has a negative charge resulting in an ionic compound. So answer choice C is incorrect making answer choice D carbon dioxide, the correct answer since carbon dioxide does not involve an ionic bond and instead, carbon dioxide is a covalent compound and the electrons are shared through covalent bonds instead of ions. So answer choice D is the correct answer. I hope you found this video to be helpful. Thank you and goodbye.
