If the substance is an element the answer is an atom. If the substance is a compound the answer is a molecule.
Molecules
An atom. Anything smaller is an atomic particle from which all elements are made.An atom is the smallest particle of an element that has properties of that element.An atom is the smallest unit of an element that retains the properties of that element.
A substance is any material or matter having specific, defined properties.
The smallest substance of Iron is itself (Fe) The smallest substance of water (H2O) is Hydrogen (H) and Oxygen (O) Compared results are Water having 1 more element than Iron. 2 elements are derived from water and only 1 from Iron.
the smallest component of an element having thechemical properties of the element, consisting of anucleus containing combinations of neutrons and protons and one or more electrons bound to the nucleusby electrical attraction; the number of protonsdetermines the identity of the element.an atom with one of the electrons replaced by someother particle: muonic atom; kaonic atom.
Atom is a smallest particle of an element that cannot exist in free state is called atom.A species having positive and negative charge is called ions.
The smallest particle of matter having distinctive chemical and physiacl properties; a tiny particle

An atom is simply the smallest component of an element having the chemical properties of the element. An aluminum atom, is simply that, the smallest part of aluminum having the chemical properties of aluminum.
A substance is any material or matter having specific, defined properties.
An atom is the smallest particle of a chemical element that retains its chemical properties. A molecule is the smallest amount of a substance that consists of a number of atoms of the same or of different elements.

Mass gets preserved (you have to consider the stuff that isn't the end produced chemical, too). Otherwise, chemical changes are known for having different properties. They could have similar properties, I imagine, but then, "Why would anybody want to make them?"

An atom is the smallest component of any element having all the chemical properties of that specific element. A compound is a substance consisting of two or more different elements. Minerals are solid homogeneous inorganic compounds having specific chemical compositions that can be represented by chemical formulas. They are different from rocks, which can be a mixture of minerals and non-minerals and do not have a specific chemical composition.
Metalliferous rocks are rocks having metallic properties. This is mostly due to abundant presence of metallic materials or substance in them.
The smallest component of an element having the chemical properties of the elementatom comes from the word atomos ( a= not/ tomos= devisible)it was called this because it was belived that all matter was made from individual descrete particles so not visible.MIT lecture on the origin of the atom,A direct answer for this..The word 'atom' means 'uncuttable' or 'smallest indivisible particle of matter
