Free essays on Atomic Theory are informative and educational documents that provide a detailed account of the development and progression of the atomic theory. These essays discuss the different contributions made by notable scientists, such as John Dalton, Albert Einstein, Marie Curie, and Niels Bohr, in exploring the atomic structure and their properties. They also examine the various experiments conducted to test and verify the atomic theory, such as the Millikan oil-drop experiment, Thomson’s cathode ray tube experiment, and Rutherford’s gold foil experiment. These essays provide an in-depth analysis of the atomic theory and its significance in shaping the modern understanding of the physical world at the atomic and subatomic level.
A History of the Atomic Theory
The atomic theory was a theory based on the idea that every item in this world could be broken down into an extremely small particle called the atom. If the idea had never been presented and recorded, then there would have been no attempts to prove it, and science would have suffered as a result Dealing with the events before the birth of Christ, the only significant scientific development was in sixth century B.C. It was the discovery of static…...

New Theories Contradicting John Dalton’s Atomic Theory
In the 1800 s, John Dalton proposed the first atomictheory. Since then, scientists have learned much more aboutthe structure of an atom, and therefore the atomic theoryhas changed. Dalton had to have a basis for his ideas about atoms. The first law he based his ideas on was the law orconservation of mass. This theory was discovered by Frenchchemist Antoine Lavoisier. He was the first to corectlydemonstrate how something burns. The law basically saysthat atoms can t be destroyed or…...

An Analysis of the Atomic Theory in Ancient Greece and the Modern Society
In this report I will give a history on the development of the atomic theory. I will cover some of the most important dates in the development of atomic theory. An atom was first thought of by the Ancient Greeks who believed that matter was made of smaller particles called elements. The name they gave to these particles was the atom. In 1776 the man known as "The Father of Atomic Theory", John Dalton was born in England. He is…...

Explaining the Atomic Theory
Water, earth, fire, air, long ago were once known as the four main elements. Ancient Greek philosopher Aristotle contributed to the theory by adding a fifth element, aether. Before Aristotle though, the Greek believed everything was made up of the four elements. Hippocrates used the four elements to describe the four humor theory he proposed himself. Despite all the belief in the theory of the four elements, soon it was discovered that the four elements theory was wrong. Near the…...

US Government Created the Manhattan Project to Test the Atomic Theory
The year was 1945. The war in the Pacific had reached its climax with the attack on Pearl Harbor, or so the world thought! In 1943 a new era was just being discovered when Albert Einstein had uncovered a new way of destroying things. One so powerful it could wipe out entire cities in seconds. When Albert told the president of the U.S.A. he had no idea of what the army was going to do with that knowledge, the knowledge…...

The Rutherford Atomic Theory
Rutherford was born on August 30, 1871, in Nelson, New Zealand. He was educated at the University of New Zealand and the University of Cambridge. He was a professor of physics at McGill University in Montreal, Quebec from 1989 to 1907. He was also professor at the University of Manchester in England. After 1919 he was professor of experimental physics and director of the Cavendish Lab at the University of Cambridge moreover held a professorship, after 1920, at the Royal…...

The Important Advances in the Discovery and Development of the Atomic Theory
The atomic theory has advanced since the discovery of radioactivity in 1898. And so much of modern technology is based on these advancements. They couldn't have happened without the discovery of electrons (e), protons (pt), and neutrons (no) through experiments done by four key scientists. Atomic theory starts to develop in 1897 when J. J. Thomson discovered the e through his cathode ray experiment. In this experiment (figure one) he had a partially evacuated tube (a) with a cathode (b)…...

The Early Life, Successes and Contributions of John Dalton in Atomic Theory
John Dalton once made this famous quote on his work concerning the atom, We might as well attempt to introduce a new planet into the solar system, or to annihilate one already in existence, as to create or destroy a particle of hydrogen. John Dalton was a British chemist and physicist, who developed the atomic theory upon which modern physical science is founded. Dalton, a Quaker, was born on September 6, 1766, in Eaglesfield, Cumberland County, England. He received education…...

The Contributions of John Dalton in the Field of Science
Dalton, John (1766-1844), British chemist and physicist, who developed the atomic theory upon which modern physical science is founded. Dalton was born on September 6, 1766, in Eaglesfield, Cumberland County, England. He was the son of a weaver and received his early education from his father and at a Quaker school in his native town, where he began teaching at the age of 12. In 1781 he moved to Kendal, where he conducted a school with his cousin and his…...

Brilliant Scientists and Atomic Theory
Development of the Modern Atomic Theory The modern atomic theory we have today came from contributions of many different scientists. Democritus, Dalton, Thompson, Millikan and Rutherford all had their specific contributions to the development of the Atomic theory we have come to know today. Democritus, for example, developed and named the building blocks of matter atomos, meaning literally "indivisible," about 430 BC. Democritus believed that atoms were uniform, solid, hard, incompressible, and indestructible and that they moved in infinite numbers…...

John Dalton’s Biography and Contribution to Science
John Dalton was born in September 5,1766 in Eaglesfield in Cumberland, England. Dalton and his family lived in a small country house. His family had been Quakers since 1690. Quakers where members of a society of friends. John had a brother named Mary and A brother named Charles, when he was born his brother was twelve years old and his sister was two years old. Dalton's birth was not recorded, so when he grew up older he asked one of…...

A Highlight of Popular Scientific Experiments on Atoms
In the beginning of the 1800s John Dalton, an English scientist did work some work on gases, which lead him to the creation of a complex system of symbols for all known elements at the time. He took all the information he had collected, along with the Laws of Conservation of Mass, Definite Composition and Multiple Proportions and updated Aristotle's theory of matter with the Atomic Theory of Matter, which stated: All matter is composed of tiny, indivisible particles called…...
