To determine which molecule is not tri-atomic, we need to identify examples of tri-atomic molecules (which have three atoms) versus those that have a different number of atoms. Common tri-atomic molecules include water (H₂O) and carbon dioxide (CO₂). A diatomic molecule, such as oxygen (O₂), consists of only two atoms, while a tetra-atomic molecule, like methane (CH₄), has four. Therefore, any diatomic or tetra-atomic molecule listed would not be tri-atomic.
