The prefix tri- means three.
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.

The prefix before an element typically indicates the number of atoms of that element present in a compound or molecule. For example, in chemistry, prefixes like "di-" or "tri-" specify that there are two or three atoms, respectively. In other contexts, such as biology or linguistics, prefixes can modify the meaning of a root word, providing additional context or denoting a specific characteristic. Overall, prefixes serve as a shorthand to convey important information about quantity or meaning.
