So far, the "quark" is believed to be the most tiny fundamental particle.
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
observable ? i'd say quarks.
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.
Particle Physics
QUARKS are the smallest particles.they r known to be smaller than electrons,neutrons and protons.discovered way back in the 20th century
A quark is the smallest particle in matter.
An atom is the smallest particle of a substance.
The smallest particle of an element is called an atom.
The atom is the smallest known particle.
The Standard Model of Particle Physics gives a good list of particles and their masses.
The smallest particle in the atom is the electron.
