Question

Is oxygen stable or unstable?

Answer 1

1. The electronic configuration of oxygen is 1s²2s²2p⁴.
2. From electronic configuration, it is clear that oxygen has four electrons in its p-orbital which means either completely full filled or half-filled.
3. Oxygen atoms can form the oxides by the interaction with some other compound or element.
4. An oxygen molecule is comparatively more stable than an oxygen atom.

Hence, oxygen is not a stable atom.
