Actinium (Ac) is an atom.
One atom; actinium is an element, not a molecule.
Actinium does not form a common molecule like many nonmetals do; instead, it typically exists in metallic form or as part of compounds. As a member of the actinide series, actinium primarily occurs in the form of actinium(III) compounds, such as actinium oxide (Ac2O3). These compounds can form when actinium reacts with oxygen or other elements, but it does not have a stable, common molecular structure like diatomic or triatomic molecules found in other elements.
