Democritus was a very simple man like all of the other people in ancient Greece. Life was hard for everyone‚ unlike today‚ where it is like we all live inn paradise compared to them. However‚ in many ways‚ the Greeks were more advanced that we are today. They revolutionized society by making advances in philosophy‚ language‚ literature‚ mathematics‚ and of course‚ science. They produced some of the brightest minds known to man‚ including Democritus. Democritus made many very important discoveries

Thomson discovered the electron. He continued studying the atomic theory to come up with an improved atomic theory and “The Raisin Bun Theory.” Thomson’s atomic theory was that “matter is composed of atoms that contain electrons (negative particles) embedded in a positive material. The kind of element is characterized by the number of electrons in the atom.” Dalton is known as the one who developed the atomic theory and although some of his theories are proved false today‚ his “pioneer work” helped many

The scientist we chose for our project is John Dalton. Who is John Dalton‚ you might ask? John Dalton was an English chemist‚ physicist‚ and meteorologist. He is best known for the discovery of the modern atomic theory. The rules for the atomic theory are that all matter is made up of tiny particles‚ or atoms‚ atoms are always invisible and indestructible‚ all atoms of a given element are identical in mass and properties‚ compounds are formed by a combination of two or more different kinds of atoms

Ashley Buss Chemistry Mrs. Hyde 9/27/13 Aspect 1: Our class conducted 3 experiments to demonstrate‚ investigate and experimentally verify the Atomic Laws of Dalton’s Atomic Theory. In our first experiment‚ we measured the mass of 2 objects and then added them and measured the combined mass. We did this to learn about the Conservation of Mass. In our second experiment‚ we took 2 packages of Oreos (regular/double stuf). We weighed the mass to determine the ratio. We did this to model the Law

Chemistry: Atom structure theories Scientific research is a multistage and complicated process which requires many creative minds to contribute into its creation in order to be efficacious and present solid results. I’ve been given an information sheet apprising ideas of four scientists whose work was very significant in creating the theory about atom structure we recognise nowadays. Guiding Questions: 1 What significant contribution did each of the following people make to present ideas about the

matter and all life. The history of the study of the atomic nature of matter is the thinking process that goes on in the scientist’s heads. Further progress in the understanding of atoms did not occur until very famous scientist created the atomic theory. Here are some scientists who changed the way we learn about the atom‚ and the atomic nature of all life. Ernest Rutherford. Ernest Rutherford was another scientist that changed the atomic model. Rutherford was studding physics up until his

considering how hard she worked. 6. A scientist does not jump to conclusions Example: John Dalton’s atomic theory was backed by experimental evidence. He was not the first to propose that the atom was the smallest particle of matter‚ but he was the first to use experimental evidence to support his theory. 7. A scientist is a creative and critical thinker Example: Albert Einstein was able to derive his theory of relativity because he went beyond what was given and known at that time. He saw links and connections

physicist‚ and meteorologist. Dalton was born in 1766. He is best known for his work in color blindness‚ and of course‚ his Atomic Theory. His theory gave us an idea about what the universe is really made up of‚ and he paved the way for many more important scientific discoveries after he died in 1844. His theory was simple: He stated that all matter is made of atoms. He based his theory on two laws: the law of conservation of mass and the law of constant composition. The law of conservation of mass says

the atom‚ it has involved and formed many theories. There were many physicians who were significant people that contributed to the formation of the atom today. One of these physicians is named John Dalton. He should be considered as the most influential contributor to the atomic theory‚ due to the fact that he was one who formulated various theories that assist in defining the atom. There could have been numerous ways for Dalton to disarray the theories‚ and yet he did not.
