No. The individual components of the atom are also considered matter.
As for what the smallest particle is, we have gone past the electron and are now at the level of a quark. In 20 years, the answer may probably change again as we get better and better at seeing deeper into what makes matter.
No, an atom is not the smallest particle with mass. The atom is made up of smaller particles (protons, neutrons and electrons), and these also have mass. Further, protons and neutrons are made up of fundamental particles called quarks. Quarks and electrons are fundamental particles, and are smaller than an atom.
well the smallest atom is the solid or crystal to my knowledge
Protons and neutrons are made up of 3 quarks each. Hence a quark is the smallest particle in an atomic nucleus
There are somethings that are smaller than atoms (e.g. the electrons, protons and neutrons that make up the atoms) but atoms are fundamental (basic) particles that make up everything else.
The atom is the smallest particle of an element that retains the chemical and nuclear properties of the element.
Element.
An atom is the smallest particle of a substance.
An iron atom is the smallest iron particle that still has the properties of iron.
This particle is the atom.

An atom is the smallest particle that comprises a chemical element.Source:http://en.wikipedia.org/wiki/Atom
The atom is the smallest known particle.
The smallest particle of an element is called an atom.
The smallest particle in the atom is the electron.
An atom is the smallest particle of a substance.
An atom is a particle, the smallest particle that can exist by itself.
An iron atom is the smallest iron particle that still has the properties of iron.
An atom is the smallest particle of an element that can be uniquely identified as that specific element.Note that this question is different from asking "What is the smallest particle in an atom?" (see related question below). Atoms are composed of smaller particles (protons, electrons, and neutrons), but the smallest thing that has the identity of a specific element is the atom.The smallest particle of an element that still retains all that element's properties is called an ATOM.
atom is the smallest particle of matter
Atoms are NOT the smallest particle- they are the smallest COMPLETE particle. In an atomic reaction, the atoms are broken apart, and release energy.
