There was also a big focus on the creation of a universal medicine (panacea) that would cure all diseases and heal the body and soul. periodic table, in full periodic table of the elements, in chemistry, the organized array of all the chemical elements in order of increasing atomic. And for chemistry, no cause for celebration surpasses the origin of the periodic table of the. A common pursuit of alchemists throughout history was the creation of a potion for immortality or the philosophers stone, a proposed elixir or element that would allow the user to live forever. Astronomy fans commemorate 1543, when Copernicus placed the sun at the center of the solar system. We can break atoms down into different element by the process of radioactive decay but this can be dangerous and hard to control.ДЄlchemy also focused on the creation of elixirs and potions for humans. The closest we can get to this is nuclear fusion where the nucleus of an element is collided with another to form larger elements, but we cannot do this on earth yet due to the large temperatures and pressures required, the only place we know of that this occurs is in the sun when hydrogen atoms are combined to form helium. Attempts to classify elements and group them in ways that explained their behavior date back to the 1700s, but the first actual periodic table is generally credited to Dmitri Ivanovich Mendeleev, a Russian chemist who in 1869 arranged 63 known elements according to their increasing atomic weight. We know today that this is not possible as to change one element into another we would have to change the number of protons. One branch of alchemy was transmutation the turning of base metals such as lead into precious metals like gold.

Alchemy is the forefather of modern chemistry and includes the influences of many countries across the world from China and India in the east to Egypt and Greek empires in the west, through to medieval times.ДЄlchemy had many aims but primarily was used to describe the manipulation of materials and the practice of chemistry as it was known. It comes from the old French term вЂalkimieвЂ™ and the Arabic вЂal-kimiyaвЂ™ which translates as fusing or casting metals. Alchemy is an old term used to describe the manipulation of matter.
