Because there are smaller things
Atoms
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 named his smallest piece of gold "atom," which means indivisible in Greek. This concept eventually led to the development of the modern atomic theory.
The smallest piece that water can be divided into and still be considered water is a water molecule, which consists of two hydrogen atoms bonded to one oxygen atom.
Because any matter that pulls you to one side will be compensated by another piece of matter that pulls you in the opposite direction.Because any matter that pulls you to one side will be compensated by another piece of matter that pulls you in the opposite direction.Because any matter that pulls you to one side will be compensated by another piece of matter that pulls you in the opposite direction.Because any matter that pulls you to one side will be compensated by another piece of matter that pulls you in the opposite direction.

An Atom.
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.
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 called the smallest piece of matter "atoms" because in Greek, "atomos" means indivisible or uncuttable. He believed that all matter was made up of these tiny, indivisible particles that couldn't be divided any further.
He was using this to compare it to the smallest part of an element ... an atom which he called "atomos" from the Greek origin
An atom is the smallest piece of matter that retains the properties of an element. It consists of a nucleus (protons and neutrons) surrounded by electrons. Each element has its own unique type of atom.

The smallest particle of an element that still has all the properties of an element is an atom of that element.
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.
