Three years later he married a friend of the family Geneviève Nicolas, with which he had seven children. Despite his teachings as an engineer and extensive background in the industrial sector, he chose to teach chemistry after finding that working as a mining engineer in the province was not all he thought it would be. In 1877 he returned to the Ecole des Mines so he may teach chemistry and in 1887 became appointed the head of general chemistry at the Ecole de... ... middle of paper ... ...d more nitric acid to fill what had been taken out. 3d: If the pressure of the whole system is increased due to a deceased in the volume of the reaction vessel then the equilibrium of the reaction will shift towards the left. Because based on Le Chateliers principle if there is an increase in pressure then the equilibrium shifts towards the side which would produce a lower number of particles.
He worked hard to earn a doctorate in physics in 19911 which he received from Copenhagen University. The next year, 1912, Bohr was working for Nobel laureate, J.J. Thompson, in England. He was introduced to earnest Rutherford whose discovery of the development of an atomic model and nucleus had given him a Nobel peace prize in chemistry in 1908. Bohr began to study the properties of atoms under Rutherford’s tutelage. Rutherford and Planicks theory needed help with their theory and description so Niels Bohr helped explained what happened inside of the atom and developed a picture of atomic structure.
This work catapulted his career as an experimentalist and captivated the minds of many great physicists. After discovering these particles by using an electrometer to measure electric current created by radiation, Rutherford wished to leave radio-chemistry behind and get back into the physics world; he began by using his latest discovery to learn about atoms and their structures. Before he could do this, he needed to learn more about the behavior and structure of the alpha particles. Ernest and his partner Hans Geiger developed a machine that could aid in the counting of alpha particles called the Geiger Counter. The men applied a voltage to a metal cylinder with a wire running through its center, then allowed particles to pass through a small window where they created gas ions by colliding with gasses.

In 1898, Marie Curie (Polish physicist) and Pierre Curie (French physicist) were one of the first scientists to isolate radium and polonium from pitchblende (uraninite). Henri Becquerel received a Nobel Prize for his work, finding radioactivity in uranium. Wilhelm Konrad Rontgen also received a Nobel Prize for discovering the X-ray. These breakthroughs aforementioned were why he turned his attention to radioactivity. His ability to work creatively, not only by himself, but also with other associates, whom most were already established in the field of science.
In order to fix this problem Alfred nobel was able to mix this liquid with silica, turning it into a paste which we know as dynamite. this was incredibly useful for mining because it could form a cylindrical shape and be put into holes created by drills for mining. So, all for all these chemist have lived their lives and were able to produce significant advances to the field of chemistry whether it be finding a new element, or creating an explosive that will revolutionize the field of mining. These people are even able to make a contributions that we use in our chemistry labs to this day in the form of a bunsen burner. These people have all lived and done great things changing the field of Chemistry forever.
Being a skilled and intelligent man in his field of nuclear science, he was one of the many scientists selected to work on Loa Alamos, New Mexico on the American project to construct the first atomic bomb. Leo Szilard, born February 11, 1898 in Budapest. He encouraged and aided Albert Einstein to write the letter to FDR about the potential military use of atomic energy. Szilard also contributed to the creation of the first controlled nuclear reaction in 1939. Frédéric Joliot-Curie, born in Paris France, March 19, 1900.
As a scientist, Millikan made numerous momentous discoveries, chiefly in the fields of electricity, optics, and molecular physics. His earliest major success was the accurate determination of the charge carried by an electron, using the elegant "falling-drop method"; he also proved that this quantity was a constant for all electrons (1910), thus demonstrating the atomic structure of electricity. Next, he verified experimentally Einstein's all-important photoelectric equation, and made the first direct photoelectric determination of Planck's constant h (1912-1915). In addition his studies of the Brownian movements in gases put an end to all opposition to the atomic and kinetic theories of matter.

In 1911 Marie was awarded the Nobel Prize in Chemistry. She received this award for the discovery of the elements radium and polonium, by the isolation of radium and the study of nature and compounds of this element (Froman).
