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...

This question is about atomic structure.There is a general trend for an increase in ionisation energy across Period 3. Give one example of an element that deviates from this trend. Explain why this deviation occurs. : Aluminium / Al(Outer) electron in (3)p orbital / sub-shell (level) (3p) higher in energy / slightly more shielded (than 3s) / slightly further away (than 3s) Give an equation, including state symbols, to represent the process that occurs when the third ionisation energy of...
