Sample Chemistry Placement Exam Questions with Certified Answers Answer: Oxygen Aluminum forms a +3 ion. In order for the formula unit Al2X3 to be electrically neutral, the element X must form a -2 ion. Nonmetals in the oxygen column do this. Of these elements, only oxygen is a diatomic gas. Aluminum reacts with element X to form a compound with the formula A2X3. Element X exists as diatomic molecules, X2, in the gaseous state at normal temperature and pressure. Element X must be? A...
