essential Discoveries in ChemistrySince the dawn of man, chemistry has been the tool used to attain our search for knowledge. A multitude of discoveries puzzle changed the way use chemistry. These discoveries atomic number 18 being made every day and they change the way we represent the universe. The following is a type of important discoveries in chemistry.1. stripping of the ingredientThe judgement that atoms make up matter has been around for centuries. However, it has only play a role in chemistry for the past 200 years, and the idea hasnt taken off until the last 100 years.Ancient Grecian philosopher, Demokritos, was one of the first to propose the idea that matter is made up of sm eitherer units. He c anyed these units, atoms. The word atom means unable to be divided. Demokritos also thought that the atoms moved through an infinite empty. Aristotle, however, believed the realness contained continuous substances his belief would be dominant for the time period.The ato m would non be scientifically theorized until 1808 by John Dalton. His atomic theory states completely matter contains indivisible and indestructible particles called atoms.The atoms of any one element have the resembling mass and properties.Compounds are the settlement of the combination of different atoms.The rearrangement of atoms results in a chemical reaction.Today, nothing in chemistry would be the same without the idea of the atom. Not only is it the basic building block of all matter, but it is also the basic building block of almost all of our knowledge in chemistry.2. Discovery of the ElectronThe electron was discovered by J.J. Thompson, a physics professor at Cambridge University.The discovery would be the result of Thompsons experiments with cathode tubes used in electric and ... ...ial agent was at its greatest. The U.S. pushed fabrication to produce the penicillin mold. Towards the end of World War II, 650 billion units of penicillin were produced every month. 7. Discovery of Water in Martian SoilA more new-fangled discovery might set the path to discovering life on other planet. Data collected by NASAs Curiosity rover shows that Martian skank holds about 2% weewee.The rovers Sample digest at Mars instrument heated a soil sample to 835 degrees Celsius. The resulting gases were oxygen, chlorine, and surprisingly, water vapor.Laurie Leshin of Rensselaer Polytechnic Institute says that a cubic foot of the soil would yield a couple pints of water. From what we know so far, this water is drinkable. However, no one has worked out how to use the soil as a imaginativeness for water. One idea is to use a condenser to cool the water vapor into a liquid.
