The smallest part of any chemical element that can exist is an atom of that element. The smallest part of a chemical compound that can exist is a molecule of that compound.
An atom is the smallest particle of a pure element. A molecule is the smallest particle of a compound.
The smallest particles of an element that can still be considered that element are atoms.
Either a molecule or an atom. Depends whether the substance is an element, or not.
A small particle of a substance cannot really get any smaller. You could call it a molecule of that substance, but the two terms are often used interchangeably.
The smallest piece of matter is the atom.
element
Democritus believed that matter could not be divided into smaller and smaller pieces forever. Eventually the smallest possible piece would be obtained. This piece would be indivisible. He named the smallest piece of matter "atomos," meaning "not to be cut."
An atom is the smallest building block of matter that retains the characteristics of that matter.
The smallest part of all matter has been identified to be a "quark."
the smallest piece of an element is called an atom
That is a molecule.
We could say what the second smallest piece of matter if we knew what the smallest piece of matter was. Since the smallest pieces of matter known are quarks-down, strange and bottom have the lowest charge -3, they can be regarded as the first, second and third smallest particles.
Atoms
An Atom.
Because there are smaller things
A quark is the smallest particle in matter.
Small matter, this can be answered depending on how you look at it, originally atoms were named because they were believed to be the smallest particle of matter and cannot be split anymore but scientists now know that subatomic particles exist such as quarks. They and others are building blocks of matter. http://www.nyu.edu/pages/mathmol/textbook/atoms.html A particle is a very small piece of matter. Particles are part of atoms. Atoms are the smallest unit of all substances.
Democritus was Greek and the Greek word for atom meant "not able to be cut"" or "indivisible".

The smallest units of matter are the subatomic particles.
live substance? a virus, keeping in mind that it needs a host to replicate.

The term 'particle' broadly encompasses any relatively small piece of matter, but in particle and nuclear physics, quarks and electrons are smallest, followed by protons, then neutrons.
