Alchemy was based off of belief that there were four major elements in nature: Air, water, fire and earth. They learned how to change basic substances into other substances.
-
Developed the atomic theory for the universe, his atomic theory anticipated the modern principles of the conservation of energy and irreducibility of matter.
-
Knowledge of natural science including physics, astronomy, meteorology, and plants and animals.
-
5 regular solids "platonic." He Solves that objects in the material world are all distinct.
-
Discovery that atoms must exist based on the relationship between pressure and volume of gas.
-
Lavoisier was the founder of modern chemistry. Clarified concept of an element as a simple substance that could not be broken down by any known method of chemical analysis and he devised a theory of the formation of chemical compounds from elements.
-
Developed atomic theory. Matter is composed of differing weights and combine in simple ratios in weight. John dalton also created the solid sphere of billiard ball model as seen in the picture.
-
The resulting table displayed a recurring pattern.
-
Found 2 types of radiation, alpha and beta. He created the solar system model. Also found that the atom consits of mostly empty space.
-
Discovered the electron. Revolutionized the atomic model. Created the plum pudding model.
-
Found that atoms are radioactive! Her theory allowed her to see how radioactive each elements are.
-
Experiements to determine the electric charge carried by a single electron.
-
Properties of the element are determined by the atomic number not by atomic weight.
-
Proposed the model of the atom.
-
explains the rydberg formula, proposed the model of the atom.
-
Albert Einstein was behind the making f the atomic bomb. The atomic bomb was created by spitting an atom by dropping a particle on the nucleus of an atom.
-
Discovery of uncertainty principle.
