No. A molecule is defined as two or more atoms bonded together.
An atom
It is a molecule with many different atoms within
it is a formula unit
The smallest particle in gold should in fact be gold. Gold is an element, Au, and thus should only contain gold atoms. You could also argue that some subatomic particle is the smallest particle in gold.
An element is an atom or molecule made of a single type of atom. A compound is a molecule made of two or more different elements.
neither a molecule or a compound
An atom
A compound can contain a single atom of gold, but a single atom of gold alone, by itself, cannot be a compound.
Hydrogen is an atom but the hydrogen molecule is diatomic.H is a single Hydrogen atom, and H2 is a molecule.
No, a single atom is an element. Combinations of single atoms form compounds.
It is a molecule with many different atoms within
A single atom of any element can not be a molecule in the strictest sense, because a molecule must contain at least one chemical bond. (This does not mean that a single atom of gas can not be a kinetic-molecular theory unit, as is true for the noble gases.) A single atom of any element also can not be a compound because that by definition must contain at least two distinct elements.
Gold is a chemical element formed from atoms.
A carbon monoxide molecule consists of a single carbon atom and a single oxygen atom.
it is a formula unit
A single oxygen atom is smaller than a molecule.
