History of Atomic Theory Essay .philosopher and pupil of. History of the Atomic Model Just as we once believed that the earth was flat, our understanding of the atom was once extremely limited. As time passes, we begin to discover more and more about the world we live in. We have come to know much about the atom over the past two hundred years through the work of numerous brilliant.

Atom History Essay An Atom is a basic unit of matter that consists of a dense, central nucleus surrounded by a cloud of negatively charged electrons. The Atom was theorized by a man named Democritus of Abdera, Thrace in between c.a 460 BC - ca. 370 B.C. Atom is derived from the Greek word “atomos”, which means to be uncuttable. He had a theory that everything is composed of “atoms.

Is atomic theory the most important idea in human history.

Atomic Theory Essay. history of the atomic theory changed multiple times. In the very beginning, Democritus was the very first to propose the existence of the particle (H). The name he would give this particle was atomos. Aristotle believed that each element of the earth; water, air, fire, and earth, would gradually become small every time they were halved. This view held up for about 2,000.Atomic Theory History The Atomic Theory first came to the surface of science around 400 B.C. by a famous philosopher named Democritus. He actually didn’t create it first, but he was the first man to adopt the Atomic Theory into the world. His Atomic Theory stated that, “ All matter consist of invisible particles called atoms or atomos. The universe consists of two elements that are atoms.Essay John Dalton's Atomic Theory. and that became the structure behind his atomic theory. In 1803, John Dalton proposed an atomic theory saying that matter is made up of atoms that are indivisible and indestructable, all atoms of one element are identical, atoms of different elements have different weights and different chemical properties, atoms of different elements combine in simple whole.


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”. However this atomic theory of Democritus was criticized by Aristotle who proposed a model based on four basic “elements” of earth, air, fire and water.This would become the base for the model that is still accepted today (Atomic Theory). Besides stating that electrons orbit a nucleus, Rutherford also discovered the proton, which makes up the nucleus of a hydrogen atom. He found that a proton has a single positive electric charge, and that every atomic nucleus has at least one proton present. Rutherford proposed the existence of the neutron.

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 word.

The five atomic theories of the past two centuries represent the sudden advancement of science in modern times. Beginning with a basic theory on the behavior of atoms to the current model, some changes have been made, and some ideas are still the same. Ancient Greek philosophers believed that everything was made up of invisible particles called atoms. Since then the theory of atoms did not.
