Question

Quizplus · Accepted Answer

Oxygen has an atomic number of 8, and silicon has an atomic number of 14. As we move down a group on the periodic table, the size of the ion increases. Since both ions have a -2 charge, the oxygen ion, being lower on the periodic table, will have a larger atomic radius than the silicon ion. Therefore, oxygen ions are larger in size than silicon ions.
