Atoms...
---> protons, nuetrons, electrons ----> up and down quirks, subatomic particles
and if you believe in string theory----. quarks are made up of vibrating springs.
The smallest units are the atoms (for elements) and the molecules (for compounds).
quarks
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.
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."
the smallest piece of an element is called an atom
The smallest piece of a chemical compound is a molecule. The smallest part of an element is an atom. The smallest part of an atom (meaning of the proton, neutron and electron, which are an atom's building blocks) is the electron. Beyond that, the quark is a fundamental building block of matter, and it makes up neutrons and protons. Quarks also explain the "particle zoo" seen before the Standard Model arose to gather the phenomenon under one theoretical umbrella.
A molecule of H2O.
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.
You think probable to atoms.
Because there are smaller things
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.
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".

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.
