Chemistry is a science that studies on the matter, the ability of information processing of matter. And interaction with the energy and matter together. Due to a variety of substances. Most of which are in the form of an atom.The property and arrangement of atoms to gather a molecule such as gas, metal, or crystal. The present chemistry has stated that structure of substances in atomic level is a determinant nature of สารทุ kinds
.Chemicals are often referred to as the science center due to the chemistry that connect วิทยาศาสตร์อื่นๆ. Together, such as physics, biology, or even the earth science.At a rate that is considered very good. However, the specific Science Digest is considered important chemical production and greatly as test objects that strong. Production of drugs to cure.
the evolution of chemistry is divided into various periods as follows:
prehistoric - ad 500
- the Egyptians as a first nation to use chemistry methods. And the word Chemeia has appeared in the Egyptian language
.- Democritus (Socrates). Comment on the structure of by reason alone. Not to see the real experiment
.- Aristotle gather theory of matter. The conclusion that matter composed 4 elements: Earth, water, wind, and fire in different proportion for different types of substances,
.
the alchemy. 500 - ad 1500 (at the beginning of this era)
.- chemists interested in alchemy it into gold. But rare success
about AD 1100
- chemical knowledge spreading into Europe. At the end of this era, chemists give attention to alchemy
.- became interested in researching the elixir therapeutic
. Generation techniques sought elixir (AD 1500 - 1600)
- is the Latrochemistry
-. Chemists tried searching elixir and the treatment of various
nowadays (AD 1627 - 1691)
.- starting from the Robert Boyle "study chemistry to chemistry,"
- Robert Boyle "study chemistry for the prosperity of the chemistry, especially" and "use experimental methods to study to test the truth and theories"
.- give up theory of Aristotle on earth, air, fire, water
- Lavoisier (AD 1743 - 1794) who initiated chemical nowadays
- star ฮ์ล. (Stahl: ad 1660 - 1734) theory Florence logistics tons (Phlogiston Theory)
.- the theory of combustion. Lavoisier. Also the theory of the Florence logistics tons to give up go
- John Dalton (AD1766 - 1844) atomic theory, which is the foundation of modern chemistry But the atomic theory must give up. The atoms act both particle and wave.
