atom
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.
The scientist who believed in an indivisible, uncuttable particle was Democritus. He proposed the concept of "atomos," which means indivisible, as the smallest unit of matter that cannot be further divided. This idea laid the foundation for the development of the modern atomic theory.
Energy from the tiniest particles of matter is called atomic or nuclear energy. This type of energy is released during nuclear reactions within the nucleus of atoms.
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.
The energy that comes from the tiniest particles of matter is nuclear energy. This energy is released when nuclei of atoms undergo processes such as fission (splitting) or fusion (combining), resulting in a release of large amounts of energy.

an atom
The tiniest thing on Earth is thought to be a subatomic particle such as an electron or a quark. These particles are fundamental building blocks of matter and are incredibly small in size, making them impossible to see with the naked eye.
Atoms are the tiniest components of all matter on Earth. They are made up of protons, neutrons, and electrons.
Democritus came up with the idea that there was an ultimately small bit of matter that could not be divided any further. He called this "atomos" for "indivisible". Much later, what we call the atom was discovered. As researchers at the time thought that it was the smallest bit of matter, they called it the "atom", after the Greek "atomos". Ever after, poor Democritus has been called wrong, as teachers gleefully point out that the atom can be divided! Yet Democritus never said that what we call the atom was the smallest bit of matter. He simply hypothesized that there would be such a thing as an indivisble bit of mattter, and it was that and that alone he called "atomos". So the Greeks did not believe any one thing was the tiniest bit of matter. They simply believed that there was such a thing, regardless as to what exactly it would turn out to be.

Early Greeks such as Aristotle believed that all matter was made of four elements: earth, air, fire, and water. They believed that these elements combined in different proportions to create all substances. This theory influenced early chemistry and philosophy.
A quark is the smallest particle in matter.
Energy from the tiniest particles of matter is called atomic or nuclear energy. This type of energy is released during nuclear reactions within the nucleus of atoms.
