-
Antoine Lavoisier
Wrote the Elementary Treatise of Chemistry. The book contained a list of elements, the most recent theories and laws of chemistry and refuted the existence of phlogiston. -
Joseph Louis Proust
French chemist who proved that the relative quantities of any given pure chemical compound’s constituent elements remain invariant, regardless of the compound’s source. Also worked with research in nutrional chemistry. -
John Dalton
His atomic theory said that elements consisted of tiny particles called atoms. It states an element is pure. All elements are different from each other due to differing masses. A compound is a pure substance due to different. -
Michael Faraday
His main discoveries include those of electromagnetic induction, diamagnetism and electrolysis.Contributed to the fields of electromagnetism and electrochemistry. -
Henri Becquerel
He discovered radioactivity and that became the focus of his work.Becquerel was awarded the Nobel Prize for Physics in 1903. -
J. J. Thomsan
Thomsan Discoverd the electron in a series of experiments designed to study the nature of electric discharge. One of Thomson’s important experimental programs focused on the nature of positively charged particles these techniques led to the development of the mss spectograph. -
Max Planck
Max Planck was a German theoretical physicist, considered to be the initial founder of quantum theory, Planck thought that energy was made of individual units, or quanta. -
Ernest Rutherford
Rutherford, Hans Geiger and Ernest Marsden carried out the Geiger-Marsden experiment.The results of this experiment demonstrated the existence of the atomic nucleus and became a part of the Rutherford model of the atom. -
Marie Curie
She is best known as the discoverer of the radioactive elements polonium and radium and as the first person to win two Nobel prizes. -
Robert Milikan
He discovered the accurate determination of the charge carried by an electron.He also proved that this quantity was a constant for all electrons,demonstrating the atomic structure of electricity. -
Lisa Meitner
Discovered a new element protactinium. She work in the field of atomic physics she wrote and served on the United Nations Committee on atomic energy. -
Albert Einstein
One thing Einstein is best known for is his E=mc^2 formula.Einstein applied the general theory of relativity to model the large-scale structure of the universe. He delveloped the general theory of realitivity. -
Louis DeBroglie
DeBroglie made groundbrreaking contributions to quantum theory.In his 1924 thesis he said the wave nature of electrons and suggested that all matter has wave properties. -
Ernest Schrodinger
Schrodinger articulated the movements of electrons in terms of wave mechanics as opposed to particle leaps. He provided a way of thinking that would be incorparted into thousands of papers becoming an important part of quntam therory. -
Niels Bohr
Niels Bohr was a physicist who made contributions to understanding atomic structure and quantum theory. -
James Chadwick
Chadwick proved the existence of neutrons, preparing the way towards the fission of Uranium and the atomic bomb. -
Otto Hahn
Hahn discovered the fission of uranium. -
Glen T. Seaborg
Was involved in identifying nine transuranium elements. Specifically, he identified element 93, neptunium, among the fission products of uranium.
