which image does not represent a molecule? n≡n o==s==o ag
Answer
Brief Explanations:
A molecule is formed by the combination of two or more atoms held together by chemical bonds. $N\equiv N$ is a nitrogen - nitrogen triple - bonded molecule, $O = S=O$ is a sulfur - oxygen double - bonded molecule, and $TiCl_4$ is a molecule with titanium bonded to four chlorine atoms. Silver ($Ag$) is an element and exists as individual atoms in its elemental form, not as a molecule.
Answer:
$Ag$
