     When we learn chemistry; our teacher teaches us the two most important rules of chemistry that are ' OPPOSITES ATTRACT EACH OTHER'  & ' LIKE' DISSOLVES 'LIKE'  but guys do you know these two rules of chemistry are also applicable to our lives; in our life, we meet many people among them we get to attract the opposite gender, we fall for them but when its time to dissolve in them we need the same level of thinking, when we both guys have the same thinking we can survive our lives peacefully, cheerfully and happily.    Guys, we learn chemistry in deep we get to know that opposite charges attract each other and same charges repel each other. Two opposite charges form a bond together and make a new compound with different properties; but like dissolves like is totally different than this, when its' time to dissolve only like solute and solvents dissolves each other such as polar dissolves polar, non-polar dissolves non-polar and form a new solutio...

                       From the very first moment humans appeared on the planet, we have attempted to understand and explain the world around us. The most insatiably curious among us often have become scientists. Here is the list of the 100 most influential scientists of all time.   Asclepius Hippocrates   Aristotle   Pliny the Elder Ptolemy   Galen of Pergamum   Avicenna   Roger Bacon  Leonardo da Vinci    Nicolaus Copernicus  Paracelsus  Andreas Vesalius  Tycho Brahe  Giordano Bruno  Galileo  Johannes Kepler  William Harvey  Robert Boyle  Antonie van Leeuwenhoek  Robert Hooke John Ray  Sir Isaac Newton  Carolus Linnaeus  Henry Cavendish  Joseph Priestley  Luigi Galvani Sir William Herschel   Antoine-Laurent Lavoisier  Pierre-Simon Laplace Edward Jenner  John Dalton  Georges Cuvier...

                           It was the time of the revolution of chemistry & now chemistry is growing older & older. At the beginning of the 19th century, the chemistry was divided between those who followed the atomic theory & those who didn't. Well before the dispute had been settled, many had already applied the concept of atomism to chemistry. Svante Arrhenius gave ion theory which anticipated ideas about atomic substructure that didn't fully develop until the 20th century.                  Atomic theory, stoichiometry, table of atomic weights (where oxygen used as a standard), the classical system of chemical symbols & notation, radical theory of chemical combination, development in the field of electrolysis, the discovery of metal like sodium & potassium (first metal that isolated by electrolysis discovered by Davy in 1807), the invention of the Dav...

                                       This period ended with the book THE NATURE OF THINGS( DE RERUM NATURA) written by Roman poet and philosopher Lucretius (50 BCE) & Pliny the Elder described the early development of purification methods in his book Naturalis Historia. People thought that these suits ended & they are much familiar with chemistry, but it made chemistry more complicated; philosophers & scientists became more curious about chemistry.               It was a medieval period. People were familiar with chemistry, but they don't know more about it. There was a Persian-Arab alchemist Jabir ibn Hayyan who developed a primary elemental system. This system depended on four basic elements earth, water, fire & air in addition to two philosophical elements sulfur & mercury. The concept of tria prima was given by Swiss alchem...
