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.
a molecule, I think...
chemical element
Name 2 examples of complex molecules
I believe you are defining an "atom".
Molecules
The smallest unit,usually consisting of a group of atoms,into which a substance can be divided without a change in its chemical nature.

The maximum value of the sine function is 1 and that the smallest value for a would be pie divided by 2. So, if 2a= pie divided by 2, then the answer is a=pie divided by 4(simply divide both sides by 2).
