The electrons are negatively charged particles that orbit the nucleus’s centre. Democritus came up with the concept that matter is composed of atoms.

WebThey thought of atoms as moving particles that differed in shape and size, and which could join together. Later, Aristotle and others came to the conclusion that matter consisted of various combinations of the four “elements”—fire, earth, air, and water—and could be infinitely divided. WebAll matter is made of indivisible particles called atoms, which cannot be created or destroyed. Atoms of the same element have identical mass and physical properties. …

The basic idea that matter is made up of tiny indivisible particles is an old idea that appeared in many ancient cultures. The word atom is derived from the ancient Greek word atomos, which means "uncuttable". This ancient idea was based in philosophical reasoning rather than scientific reasoning. Modern atomic theory is not based on these old concepts. In the early 19th century, the scientist John Dalton noticed that chemical elements seemed to combine with each other by …
