Democritus
The concept of an atom was first proposed by Democritus in the 5th century BCE. But he was ignored until the start of the 19th century that an English chemist named John Dalton again proposed it.
The particle theory of matter was developed by the ancient Greeks, particularly Democritus and Leucippus. They proposed that all substances are made up of tiny indivisible particles called atoms.
A quark is the smallest particle in matter.
an atom
The particle theory is called the "particle model" or "particle theory of matter." It proposes that all matter is composed of tiny particles that are in constant motion.
This particle is the atom.
The smallest particle of matter is called an atom. It is the basic unit of a chemical element and retains the properties of that element.
The wave-particle duality of matter was introduced by French physicist Louis de Broglie. He proposed that particles, such as electrons, could exhibit both wave-like and particle-like behavior. This idea helped lay the foundation for the development of quantum mechanics.
A piece of matter moving through space is called an object or a particle.
A BC (Boson-Catalyst) particle is a hypothetical particle proposed in theoretical physics that could potentially function as a catalyst for certain kinds of reactions. As this particle exists only in theoretical models at this point, its specific class of matter would depend on the theoretical framework in which it is being discussed. It is not a well-established part of the current understanding of particle physics.
The hypothetical particle called the Higgs boson is also known as the "god particle", pressumably because of its important role.
