-
He hypothesized that all matter (plus space and time) is composed of tiny indestructible units, called atoms.
-
He found that mass is conserved in a chemical reaction. The total mass of the products of a chemical reaction is always the same as the total mass of the starting materials consumed in the reaction. His results led to one of the fundamental laws of chemical behavior: the law of conservation of matter.
-
His theory is all matter is made of atoms, all atoms of a given element are indentical in mass and properties, compounds are formed by a combination of two or more different kids of atoms, and a chemical reaction is a rearrangement of atoms.
-
He first published his Law of Definite Proportions (or Law of Constant Composition).This law states that a compound is composed of exact proportions of elements by mass regardless of how the compound was created
-
Faraday discovered the two laws of electrochemistry: the amount of chemical change or decomposition is exactly proportional to the quantity of electricity that passes in solution; and the amounts of different substances deposited or dissolved by the same quantity of electricity are proportional to their chemical equivalent weights.
-
She collaborated with Otto Hahn in the discovery of neuclear fission and gave the first theoretical explanation of the fission process.
-
Discovery of nuclear fission
-
He was the first to discover that electrons travel in seperate orbits around the nucleus and that the numner of electrons in the outer orbit determines the properties of an element
-
The Schrodinger Equation is "the wave equation of non relativistic quantum mechanics". He showed, through math, that waves can be used to describe electrons in atoms.
-
While studying the effect of x-rays on photographic film, he discovered some chemicals spontaneously decompose and give off very pentrating rays. Discovery of radioactivity.
-
His theory was all atoms were made up of small particles, which led him to the discovery of electrons.
-
They are best known for their pioneering work in the study of radioactivity, which led to their discovery in 1898 of the elements radium and polonium.
-
Creates special and general theories of relativity, and hypothesizes about the particle nature of light. This was the basis of nuclear energy.
-
He determined the unit charge of the electron with his oil drop experiment. Thus allowing for the calculation of the mass of the electron and the positively charged atoms.
-
Identified almost ten transuranium elements.
-
Rutherford proposed the existence of the neutron.
-
He gained worldwide acclaim for his groundbreaking work on quantum theory. He discovered the wave nature of electrons and suggested that all matter have wave properties.
-
He discovered the neutron
-
Originated the Quantum theory. This theory revolutionized our understanding of atomic and subatomic processes,
-
He thought that all materials on Earth were not made of atoms, but of the four elements, Earth, Fire, Water, and Air.
