making the foundation of modern atomic theory of matter. * the idea that everything is made of distinct atoms has been a subject of skeptical discussions as recently as the beginning of the twentieth century, before Einstein’s observation of Brownian motion in 1905 and Max von Laue’s observation of the diffraction of X-rays by crystals in 1912 provided strong support for the atomistic

The History of the Atom Timeline: 400 BC He called this the theory of the universe: All matter consists of atoms, which are bits of matter too small to be seen. There is an empty space between atoms Atoms are completely solid Atoms have no internal structure Each atom (of a different substance) is different in size, weight and shape.

In chemistry and physics, atomic theory is a scientific theory of the nature of matter, which states that matter is composed of discrete units called atoms. It began as a philosophical concept in ancient Greece and entered the scientific mainstream in the early 19th century when discoveries in the field of chemistry showed that matter did indeed behave as if it were made up of atoms.

The atomic theory is developed since 2000 years ago the Greek philosopher Democritus proposed that there was a limit to how small one could be divide matter, this smallest matter indivisible particle was called “atom”.

John Dalton is now called the father of modern atomic theory for his efforts. His atomic theories were introduced in 19th century England. In September of 1803, John Dalton wrote his first table of atomic weights in his daily logbook. Two years after he developed his atomic weights, he published them in a book called “A New System of Chemical Philosophy”. In it he was the first to propose

This can be explained by atomic theory if the copper-to-chlorine ratio in the brown compound is 1 copper atom to 2 chlorine atoms, and the ratio in the green compound is 1 copper atom to 1 chlorine atom. The ratio of chlorine atoms (and thus the ratio of their masses) is therefore 2 to 1 (Figure (PageIndex{4})).
