Using the Chemistry Link to Health: Elements Essential to Health, answer each of the following:

a. What is a macromineral?

Accepted Answer

Welcome back everyone. Macro minerals are essential elements from periods three and four that must be supplied in the daily diet in small amounts. Which of the following is not a macro mineral. We have choice A which gives us oxygen choice B, which gives us sulfur. Choice C, which gives us magnesium and choice D which gives us potassium. So because we understand that macro minerals correspond to Adams in periods 3 and 4, which recall that our period numbers are the rows across our periodic table. We understand that the atom that is not a macro mineral will not be in period 3 and 4. And so, looking at our first anti choice, which is oxygen, we want to recall that oxygen is located in group 6 a on our periodic table and located across period two. And because oxygen is located in period two, we would say that it's therefore not a macro mineral. However, we want to recall that oxygen is considered a major element because it's a representative element being in period two and it's a major element which is important because they make up 96 of the body or sorry of our body mass. And we would recall that major elements are found in carbs, proteins and fats. Now, so far, we want to go ahead and place a checkmark by choice. A since oxygen is definitely not a macro mineral, it's a major element moving on to choice B. We are considering the atom sulfur recall that sulfur is located across period three and is located also in group 6 a like oxygen. Now, as we stated from our prompt, macro minerals are considered as atoms in period three and four. And so because sulfur is in period three, we would therefore consider it a macro mineral. So we would rule out choice B because again, we only want to select the choice that is not a macro mineral moving on to choice C. We're considering our atom magnesium recall that magnesium is located in group two A on our periodic table and is located across period three. So therefore, it also is a macro mineral and we can rule out choice C. And last we have choice D which considers our atom potassium, which we want to recall is located in group one, A on our product table across period four. And so therefore, it would also be considered a macro mineral, meaning we can rule out choice D. So that means that our only example that is not a macro mineral would be choice A which is oxygen as our final answer. I hope this made sense. And let us know if you have any questions.
