Verified step by step guidance1
Understand the basic concept of ions: Atoms become ions when they gain or lose electrons. If an atom gains electrons, it becomes negatively charged, known as an anion. If it loses electrons, it becomes positively charged, known as a cation.
Recall the atomic structure of oxygen: Oxygen typically has 8 protons and 8 electrons in its neutral state.
Determine the charge based on electron count: If oxygen has 9 electrons, it has gained an extra electron compared to its neutral state.
Analyze the charge: Since gaining an electron results in a negative charge, oxygen with 9 electrons is negatively charged.
Conclude the type of ion: Oxygen with 9 electrons is a negatively charged anion, as it has more electrons than protons.
