Step 1: I'll solve this step-by-step using the guidelines you specified:. Step 2: : Understand the Concept of Oxide Ions. An oxide ion is a negatively charged oxygen ion that forms when an oxygen atom gains electrons. To determine its charge, we need to consider the electron configuration of oxygen. Step 3: : Examine Oxygen's Electron Configuration. In its neutral state, oxygen has 8 electrons. Step 4: : Determine Electron Gain to Form Oxide Ion. To achieve a stable electron configuration like noble gases, oxygen needs to gain 2 electrons to complete its outer shell. Step 5: : Calculate the Charge. When oxygen gains 2 electrons, it becomes a negatively charged ion: Step 6: : Verify the Charge. The oxide ion now has 10 electrons (8 original + 2 gained), resulting in a -2 charge. Final Answer: The oxide ion has a charge of -2, which allows it to achieve a stable electron configuration similar to neon.
