The Bronze Age
A period during history where copper and bronze were used as the primary materials for weapons and tools. -
Robert Boyle
Robert Boyle was a natural philosopher, chemist and physicist. His work contained some alchemy, but he is regarded as the first modern chemist. He discovered Boyles Law, which details the relationship between the pressure and volume of a gas, if a temperature is constant. -
The Phlogiston Theory
The Phlogiston theory was the existance of an element called "phlogiston". He stated that phlogiston was inside of all combustible objects, and was relesed when the objects were on fire. The goal of the theory was to explain the processes of burning and the rusting of metals. These two processes are now known as oxidation. -
The Elixir of Life
Is a mythical drink that gives the drinker eternal life or youth. Many alchemists tried to create this mixture. In various myths, heros were said to have drank liquid gold, and were granted imortality. -
The Philosophers Stone
The philosopher's stone is the long sought after alchemical substance, said to be able to turn base metals into gold or silver. The philosophers stone was the most sought after substance in alchemy for many centuries. The efforts of the alchemists to discover the philosophers stone is known as the Magnum Opus -
Henry Cavendish
Henry Cavendish was the scietist who discovered hydrogen, or "inflammable air" as he called it. He recorded how hydrogen formed water on combustion in one of his papers. He also measured the earths density in the Cavendish Experiment -
Joseph Priestley
Joseph Priestley is credited with the discovery of oxygen, after he isolated it in its pure state of gas. He also invented sodawater. -
Antoine Lavoisier
Atoine Lavoisier was a french scientist who is known as "The Father of Modern Chemistry. He named oxygen and hydrogen, and compiled the first list of elements. He was the first scientist to establish that sulfur was an element, and not a compound, as was previously thought. He determined that even though matter can change shape or form, its mass remains constant. -
Amedeo Avogadro
Amedo Avoagdro was an Italian scientist who determinded Avoadro's Law, which states "Under the same condition of temperature and pressure, equal volumes of all gases contain the same number of molecules.". -
Jaques Charles proposes Charles Law
Jaques Charles proposes Charles Law, which states "At a constant pressure, the volume of a given mass of an ideal gass increases or decreases by the same factor that its temperature increases or decreases". -
Joseph Proust proposes law of definate proportions
Joseph Proust proposes law of definate proportions, which states that "elements allways combine in small, whole number ratios to form compouds". -
John Dalton
John Dalton was an English scientist. He is well known for his pioneering scientific works in modern atomic theory, and his reaserch into colorblindness. -
Jons Jakob Berzelius Proposes Chemical Symbols
Jons Jakob Berzelius proposes the use of the modern day chemical symbols. He also proposes the idea of atomic mass. -
Wiliam Prout proposes Prout's hypothesis
Wiliam Prout proposed Prouts Hypothesis, which states that all elements are conglomerations of hydrogen. -
Michael Faraday isolates benzene
Micheal Faraday Isolated benzene, which is the first know aromatic hydrocarbon. -
JJ Thomson
Sr Joseph John Thomson was a British scientist who discovered the electron, and isotopes. He recieved a Nobel Prize for his discoveries. -
Lothar Meyer Designs the first periodic table
Lothar Meyer designs the first periodic table, which contains 28 elements, that are organized by their valence -
Ernest Rutherford
Was a chemist from New Zealand. He was awarded the Nobel Prize in Chemistry Nobel Prize in 1908 "for his investigations into the disintegration of the eledisintegration of the elements, and the chemistry of radioactive substances". He also determined that the positive charge in the atom is found in the nucleous. He later discovered and named the proton. -
Svante Arrhenius Develops the Ion Theory
Svante Arrhenius developed the ion theory, in an attempt to explain why inelectrolytes could conduct electricity. -
Niels Bohr
Was a Brittish scientist, who developed the modern atomic model, the bohr diagram. -
Alfred Werner discovers the structure of cobalt.
Alfred Werner discovered the structure of cobalt, which established the field of coordination chemistry. -
Wiliam Ramsy Discoverys Noble Gasses
Wiliam Ramsy discovered the noble gasses, which filled out the periodic table, and led to discoveries on chemical bonding. -
Pitchblend
The elements polonium and radium were first found in the mineral pitchblend by Pierre and Marie Curie. Pitchblend was later used as a source of uranium that was needed to create the atomic bomb. -
Mihhail Semyonovich Tsvet invents Chromatography
Mihhail Semyorovich Tsvet invented chromatography, which is a method of seperating a mixture of solutions. -
Fritz Haber and Carl Bosch develop the haber process
The Haber process for making amonia from its elements, nitrogen, hydrogen and ironsubstrate. -
S.P.L.Sorenson invents to concept of pH
S. P. L. Sorenson came up with the concept of pH, and came up with several methods of measuring acidity. -
Sir James Chadwick
Sir James Chadwick was the main brittish scientist who worked on the Manhatten Project. He also woked on the ionization of phosphorus. He is also credidted with discovering the nuetron. He also developed the modern atomic model. -
Otto Han discovers the process of nuclear fission.
Otto Han discovered the process of nuclear fission, which is the process of splitting apart the nucleous of an atom. He discovered this process in uranium and thorium. -
Neil Bartlett Synthesizes xenon hexafluroplanite
Neil Bartlett synthesized xenon hexafluroplanite, which is the first time that it had been shown that noble gasses can form chemical compounds. -
Bucky Ball
A bucky ball is the atomic makeup of an allotrope of carbon. The first bucky ball was created in 1985.
