The electronic configuration of oxide ions depends on the charge of the ion. An oxide ion is typically formed when oxygen gains electrons. Oxygen has an atomic number of 8, meaning a neutral oxygen atom has 8 protons and 8 electrons. Oxide ion (O²⁻): This ion has a charge of -2, meaning it has gained 2 electrons. A neutral oxygen atom has the electronic configuration 1s²2s²2p⁴. When it gains 2 electrons, the total number of electrons becomes 8 + 2 = 10. The electronic configuration of the oxide ion (O²⁻) is 1s²2s²2p⁶. This configuration is isoelectronic with Neon. Send me the next one 📸
