검증된 단계별 안내1
Identify the normal number of electrons in a neutral oxygen atom, which is 8, as oxygen has an atomic number of 8.
Understand that an atom becomes an ion when it gains or loses electrons, resulting in a net charge.
Determine the change in the number of electrons: if oxygen has 9 electrons, it has gained 1 extra electron compared to its neutral state.
Recognize that gaining electrons results in a negative charge, as electrons are negatively charged particles.
Conclude that an oxygen atom with 9 electrons is a negatively charged anion, as it has more electrons than protons.
