an atom of sugar
A molecule is the smallest part of a compound that still retains the properties of said compound. As the atom is the smallest particle of an element into which it can be divided and still retain all the properties of that element, the molecule is the atom's analog for a compound.
This is the molecule of water - H2O.
No. Water is composed of two hydrogen atoms, and one oxygen atom. Both of these can exist as pure elements in the form of H2 and O2, respectively. Since a hydrogen (H) atom has the fewest number of protons and electrons, at one a piece, H2, the binding of two of this smallest atom, is the smallest molecule.
This is the water molecule H2O.

A molecule of H2O.
the smallest possible piece of water would be one water molecule. (one molecule of H2O), consisting of 2 Hydrogen atoms and 1 oxygen atom. Anything smaller, and it would lose the characteristics of water.

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.
There are two definitions that can answer particulate identity at its singular unit. If the given is a pure element, the smallest particle retaining identity would be the individual atom (or diatomic molecule in some gases as in O2). If the substance is a molecular compound such as water, its smallest identifying unit would be a single H20 molecule.
an "element" can be divided until it reaches a single atom. But a "molecule" can only be divided until it is a single molecule. For instance, water, H2O, is usually present in the millions to look like water. However, if you divide it up into smaller and smaller portions, say halves, you can only divide it until you have 2 Hydrogens and 1 Oxygen. If you divide it further, it is no longer water. It will become something else.

particles called atoms are the smallest unit. Several atoms combine to make a molecule and molecules are what form substances such as water
