John Dalton provided the basic theory about the nature of matter.
An atom is the basic unit of matter, consisting of a nucleus containing protons and neutrons, surrounded by electrons. The concept of the atom was first proposed by ancient Greek philosophers such as Democritus and Leucippus, but modern understanding of the atom was developed in the late 19th and early 20th centuries by scientists like J.J. Thomson, Ernest Rutherford, and Niels Bohr.
Democritus is a Greek philosopher (born c. 460 --- died c. 370 BC). Though only a few fragments of his work survive, he was apparently the first to describe invisible "atoms" as the basis of all matter. His atoms --- indestructible, indivisible, incompressible, uniform, and differing only in size, shape, and motion --- anticipated with surprising accuracy those discovered by 20th-century scientists. For his amusement at human foibles
•460 B.C. did a Greek philosopher, Democritus, made the idea of atoms. He asked this question: "If you break a piece of matter in half, and then break it in half again, how many breaks will you have to make before you can break it no further?" Democritus thought that it ended at some point, a smallest possible bit of matter. He called these basic matter particles, atoms. I doubt he had any opinion on that.
Around 460 B.C. a Greek philosopher called Democritusdeveloped the idea of atoms. He asked this question: If you break a piece of matter in half, and then break it in half again, how many breaks will you have to make before you can't break it anymore. He thought that it ended at some point, a smallest possible bit of matter. He called these basic matter particles atoms.

The ancient Greek philosopher Democritus.
Democritus, an ancient Greek philosopher, is known for proposing the concept of atomism - the idea that all matter is made up of tiny, indivisible particles called atoms. His ideas laid the foundation for modern atomic theory and influenced the development of scientific thought in fields such as chemistry and physics.

False. Democritus was an ancient Greek philosopher who proposed the idea of atoms as the basic building blocks of matter. The forces that hold together the nucleus were discovered much later by scientists studying atomic structure.
He asked the question: If you break a piece of matter in half, and then break it in half again, how many breaks will you have to make before you can break it no further? Democritus thought that at some point one would get to a smallest possible bit of matter. He called these basic matter particles, atoms. Atom in Greek means "indivisible".
