-
His idea was that every single object was made with atoms. Asl osaid that atoms can't be destroyed or differ in size.
-
He published the Law of Define Proportions.This law states that a compound is composed of exact proportions of elements by mass regardless of how the compound was created.
-
Invented the Law of Conversation.The law states that matter cannot be made or destroyed. He also hints at the rearrangement of matter in reactions. Matter rearranged, but never disappeared.
-
Proposed an "atomic theory" with sperical solid atoms based upon measurable properties of mass. He came up with three distinct states, elastic fluids, liquids and solids.
-
Studied the effect of electricity on solutions, which is "electrolysis" as a splitting of molecules with electricity, developed laws of electrolysis.
-
He discovered radioactivity.
-
Created a model called "raisin cake" in which thousands of negatively charged swarm in a massless positive energy cloud.
-
They studied uranium and thorium and called their spontaneous decay process "radioactivity". Pierre discovered radioactive elements called polonium and radium.
-
He published papers on entropy, on thermoelectricity and on the theroy of dilute solutions.
-
His famous equation E=mc3 confirmed that atoms can be broken apart.
-
His earliest success was that determination of a charge carried by an electron using "falling-drop method."
-
Using alpha particles as atomic bullets, he established that the nucleus was very dense, very small and positivly charged
-
He explained what happens inside an atom and developed a picture of atomic structure. Also he was the first person to discover that electrons travel in sperate orbits.
-
Developed the wave mechanics theory.The theory improved ourknowledge of the physical nature on the atomic scale.
-
He views electrons as continuous clouds and introduced "wave mechanics" as a mathematical model of the atom.
-
Using alpha particles discovered a neutral atomic particle with a mass close to a proton. This is how the nuetron was discovered.
-
Discovered the splitting of the atomic nucleus with Uranium and Thorium. This became known as Fission.
-
Synthesized 6 transuranium elements and suggested a change in the layout of the periodic table.
-
Didn't believe in atomis theory.He thought of 4 elements fire, earth, water, and air.
