SAMPLE CHEMISTRY PLACEMENT EXAM QUESTIONS WITH COMPLETE SOLUTIONS 100% 2023/2024 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. Elem...
