Chem1 Tutorial on chemistry fundamentals Part 1 of 5. An element is an actual physical substance that cannot be broken down into a simpler form, and is capable of an independent existence as observable matter. As such, the concept of the element is a macroscopic one that relates to the world that we can observe with our senses. The atom is the microscopic realization of this concept; that is.

Dalton’s Atomic Theory. Due to the lack of technological setup back then, scientists had very limited information on this theory. Almost after two thousand years, the works on the simplifying matter was materialized by scientist, John Dalton. In 1808, John Dalton.
Dalton’s Atomic Theory From 1803 to 1808, John Dalton, an English schoolteacher, used the two funda-mental laws of chemical combination just described as the basis of an atomic theory. His theory involved three assumptions: 1. Each chemical element is composed of minute, indivisible particles called atoms.

Although a schoolteacher, a meteorologist, and an expert on color blindness, John Dalton is best known for his pioneering theory of atomism. He also developed methods to calculate atomic weights and structures and formulated the law of partial pressures.
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.
Dalton’s idea of matter is known as John Dalton’s atomic theory. Dalton first proposed his atomic theory in 1803. On the basis of Dalton’s atomic theory, "an atom is defined as the basic unit of a substance that can take part in chemical reactions."
