It would be inaccurate because atoms are made of subatomic particles, which actually make up the element. These subatomic particles have either a positive, negative, or neutral charge. The positively charged particles are called protons. The negatively charged particles are called electrons. The neutral particles are called neutrons. The protons and neutrons are grouped together in the nucleus of an atom, with the electrons orbiting around.
An ATOM. The sub-atomic particles are Protons, Neutrons. and Electrons. The protons and neutrons are collectively named 'nucleons, because they form the nucleus of an atom. The electrons are in energy shells around the nucleus.
Particle size depends on the type of particle.
The 3 main subatomic particles found in atoms are Protons, Electrons, and Neutrons. Protons and Neutrons are called "composite particles" because they themselves are made up of smaller particles called quarks.
The "subatomic" particles in atoms are usually considered to be only protons, neutrons, and electrons, although these may contain sub-subatomic particles such as quarks and gluons. Every atom of xenon contains 54 protons and 54 electrons, because 54 is the atomic number of xenon. Every atom of xenon also contains neutrons. The lightest naturally occurring and radioactively stable isotope of xenon is Xe-124. Since the mass number is the sum of protons and neutrons, the total of protons, electrons, and neutrons for this isotope is 124 + 54 or 178. The number of particles for any other isotope of xenon may be found by adding the mass number to the atomic number.
A positron is a fundamental particle because it does not consist of smaller particles, which would make it a composite particle. Fundamental particles can still decay or change identity however, but they have no (at least at this point) discernible internal structure. A proton on the other hand is a composite particle; it has an internal structure and consists of a mixture of gluons and quarks (which both are fundamental particles).

Because protons are components of the atoms.
Protons and neutrons are classified as nucleons because they are found within the atomic nucleus of an atom. They are both composed of smaller particles called quarks and are responsible for the majority of an atom's mass.
It would look very small because subatomic particles are small.
Electrons are subatomic particles. The are currently believed to be elementary particles, but that may just be because we haven't figured out how to break them open to look at the (it was once believed that atoms were the smallest particles, but we now know about quarks and other subatomic particles). Electrons are also Fermions.
because they are contained inside the subsection of the atom (nucleus.)
Because they are much smaller than an atom
It might be misleading because atoms are composed of subatomic particles such as protons, neutrons, and electrons. Additionally, quarks are even smaller particles that make up protons and neutrons. Therefore, stating that atoms are the smallest piece of matter does not account for these smaller constituents.
Not all of them are; the only direct subatomic part of the atom that is fundamental is the electron (which is a type of lepton.) Only particles made up of no smaller parts are called fundamental particles. For example, the proton (just like the neutron, except with a small difference) is not a fundamental particle because it is made of quarks, which are fundamental particles.
kinetic energy
A tiny unit of energy, used for subatomic particles, is the electron-volt (eV). Multiples, like keV, MeV, and TeV, are also used. Because the mass-energy equivalence is quite clear in the subatomic world, the mass of particles is also often expressed in electron-volts.A tiny unit of energy, used for subatomic particles, is the electron-volt (eV).
