In the history of chemistry, chemical scientist many chemical processes, the development of modern chemistry. Many are already developing alchemist alchemy. Actually discovery of chemical elements has a very long history to reach the peak. The creation of the periodic table of chemical elements by someone who usually called Dmitri Mendeleev in 1869.
The roots of chemistry can be traced to the phenomenon of combustion. Fire is a mystical power that converts a substance into another substance and is therefore the main focus of all mankind. Fire is the lead man on the discovery of iron and glass. After gold was found and a precious metal, many people are interested in finding methods that can alter other substances into gold. This creates a protosains called Alchemy. Alchemy was practiced by many cultures throughout history and often contain a mixture of philosophy, mysticism and protosains.
Alchemist discovered many chemical processes that lead to the development of modern chemistry. Over history, the alchemist to develop away from the philosophy of alchemy and mysticism, and develop a more systematic approach and scientific. The first alchemist who is considered to apply scientific methods of alchemy, chemistry and alchemy distinguish.
Nevertheless, the chemistry as we know it today was created by a man named Antoine Lavoisier with the law of conservation of mass in the year 1783. The discovery of chemical elements has a long history culminating with the creation of the periodic table of chemical elements by Dmitri Mendeleev in 1869. As already indicated above.
Nobel Prize in Chemistry created in 1901 gives a good overview of chemical discovery over the last 100 years. At the beginning of the 20th century, revealed the nature of subatomic and atomic science of quantum mechanics began to explain the physical properties of the chemical bond. In the mid-20th century, chemistry has grown up to be able to understand and predict the biological aspects that widened into the field of biochemistry.
The chemical industry represents an important economic activity. In 2004, the top 50 producers of chemicals have global sales reaching 587 billion U.S. dollars with a profit margin of 8.1% and research and development spending 2.1% of total sales.
Well .... from information already written on this so we can menyulpulkan that chemistry is very important, from all knowledge of the chemical is very expensive to be assessed with the money, the government should be supporting people who have knowledge about chemistry. Thank You
