For a substance the term is molecule, for an element the term is atom.
The general answer would be molecule however some molecules prefer to exists as paired molecules and subdividing them would alter some of its chemical properties: a good example of this would be the sugars.
For an element, it would be an atom. For a molecular substance, it would be a molecule. If it is an ionic compound, it would be a formula unit.
For an element, it would be an atom. For a molecular substance, it would be a molecule. If it is an ionic compound, it would be a formula unit.
its either a proton, an atom, a molecule, or an element. But im not sure which one it is. So keep that in mind.
The smallest unit of a substance that has the properties would be either an atom, or more probably a molecule. An atom does not ordinarily exist by itself in nature.
It is a molecule of the substance.
Molecule
Molecule, or atom in the case of a pure elemental substance.
molecule
A molecule is the smallest unit with the characteristic properties of a molecular substance, i.e., one joined by covalent bonds. A single atom is the smallest unit with the characteristic properties of an elemental substance.
Molecule
If the substance is an element the answer is an atom. If the substance is a compound the answer is a molecule.
The smallest particle of a substance that retains all the properties of the substance and is composed of one or more atoms is a molecule.
A molecule of the substance. An atom of an element may exhibit different characteristics when it is bound to other atoms of the same element. Examples are common oxygen (O2) and ozone (O3) with altered chemical properties. Or carbon as graphite (hexagonal lattice) and diamond (tetrahedral lattice), which demonstrate very different physical properties.
A molecule is the smallest unit of a pure substance that can exist and still retain its chemical properties. An atom is the smallest unit of an element that can exist and still retain its chemical properties.
