Who Discovered Chlorine? The only problem was that those who did so did not recognize the element and did not know it then. Early Detection. This phenomenon of isolating this element and not recognizing it continued even when the man credited for its discovery produced it in an experiment. Carl Wilhelm Scheele was the first to study and isolate chlorine gas. He is credited for its discovery in 1774. However, he did not recognize it as an actual element.

Nuclear fission Nuclear fission of heavy elements was discovered on December 17, 1938 by German Otto Hahn and his assistant Fritz Strassmann, and explained theoretically in January 1939 by Lise Meitner and her nephew Otto Robert Frisch.Frisch named the process by analogy with biological fission of living cells.uclear fission produces energy for nuclear power and drives the explosion of nuclear weapons. Both uses are possible because certain substances called nuclear fuels undergo fission when struck by fission neutrons, and in turn emit neutrons when they break apart.

Cerium Element Facts / Chemistry Berzelius and Klaproth are major figures in the history of chemistry. In addition to their other achievements Berzelius discovered selenium in 1817 and thorium in 1828 while in 1789 Klaproth discovered both uranium and zirconium. Carl G. Mosander, who worked closely with Berzelius, prepared metallic cerium in 1825. First he reacted cerium sulfide with chlorine, yielding anhydrous cerium chloride. He reduced the chloride with potassium, forming potassium chloride and metallic cerium.

The History of Penicillin History of Penicillin Originally noticed by a French medical student, Ernest Duchesne, in 1896. Penicillin was re-discovered by bacteriologist Alexander Fleming working at St. Mary's Hospital in London in 1928. He observed that a plate culture of Staphylococcus had been contaminated by a blue-green mold and that colonies of bacteria adjacent to the mold were being dissolved. 1  Curious, Alexander Fleming grew the mold in a pure culture and found that it produced a substance that killed a number of disease-causing bacteria.

- Radium, in the form of radium chloride, was discovered by Marie Curie and Pierre Curie in 1898. They extracted the radium compound from uraninite and published the discovery at the French Academy of Sciences five days later.t is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals. Pure radium is almost colorless, but it readily combines with nitrogen (rather than oxygen) on exposure to air, forming a black surface layer of radium nitride (Ra 3 N 2).

It's Elemental History and Uses: 1  Iodine was discovered by the French chemist Barnard Courtois in 1811. 2  Trace amounts of iodine are required by the human body. 3  Iodine is used as a test for starch and turns a deep blue when it comes in contact with it.  Care should be taken in handling and using iodine.

- It is a common misconception that James Watson and Francis Crick discovered DNA in the 1950s. In reality, DNA was discovered decades before. It was by following the work of the pioneers before them that James and Francis were able to come to their ground-breaking conclusion about the structure of DNA in 1953. The story of the discovery of DNA begins in the 1800s….

WHO DISCOVERED DNA? It was Crick and Watson who worked out the structure of DNA in the 1950's, but its discovery was made nearly 100 years previously by a Swiss physician called Frederick Miescher.iescher discovered DNA in 1869 whilst studying pus-ridden bandages that were being sent to the laboratory by the local clinic. At this time the lab was working on the chemistry of body fluids, particularly blood. To that end the young physician was studying lymphocytes, though these were hard to obtain.
