Smallest particles in an atom are named as subatomic particles. They have been categorized into four. They are photons, leptons, mesons and baryons.
Baryons are further classified into nucleon and hyperon.
Photon is the smallest one whose rest mass is zero. Though it does not have mass, it has momentum. The energy content of a photon is mainly decided by the frequency of the radiation. So E = h v. v (nu) is the frequency
Leptons are some how heavier but lighter than mesons. Electrons, positrons, neutrino, muons all come under this category
Mesons have different types such as pi meson, eta meson, k meson etc
Baryons have nucleons (protons and neutrons) and hyperons. (much heavier than nucleon)
Apart from these there are strange particles and these are being studied and science now and then comes across new discoveries of subatomic particles. So far more than 100 particles have been discovered.

With a mass of about 9.10938215×10−31 kg. (0.510998910 MeV), Electrons are one of the smallest known particles in atoms but they are composed of quark particles.....
considering the fundamental particles- nutrinos MAY BEthe smallest particle :-(

The smallest particle of an element that retains its identity in a chemical reaction?
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.
How do you explain an atom?
atom is the smallest particle of matter
If atom are smallest particle than why atom bomb are getting blast?
Atoms are NOT the smallest particle- they are the smallest COMPLETE particle. In an atomic reaction, the atoms are broken apart, and release energy.
What is the smallest divisible particle?
the atom
