Atom
No It is not true that atoms are the smallest particles in the planets. The smallest particles are electrons, protons, neutrons, and others.
quark and anti-quark making the composition of protons and neutrons.
Atoms are NOT the smallest particle- they are the smallest COMPLETE particle. In an atomic reaction, the atoms are broken apart, and release energy.
The discovery of the subatomic particles demonstrated for the first time that atoms are not the smallest particles of matter. Electron was the first subatomic particle discovered by J.J. Thomson.
That depends. The smallest particle in the classic physics is te atom. In the modern physics is the quark (quark is the composition of an eletron). WHAT IS THE SMALLEST PARTICLE The quark
A quark is the smallest particle in matter.
An atom
subatomic particle
The atom is the smallest known particle.
This particle is the atom.

The smallest part of all matter has been identified to be a "quark."
