What is Chemistry - Chemistry is the scientific discipline involved with elements and compounds composed of atoms, molecules and ions. The term "chemistry", in the view of noted scientist Robert Boyle in 1661, meant the subject of the material principles of mixed bodies. The 1730 definition of the word "chemistry", as used by Georg Ernst Stahl, meant the art of resolving mixed, compound, or aggregate bodies into their principles; and of composing such bodies from those principles. Antoine-Laurent de Lavoisier is considered the "Father of Modern Chemistry’. In the scope of its subject, chemistry occupies an intermediate position between physics and biology.
The word chemistry comes from alchemy, which referred to an earlier set of practices that encompassed elements of chemistry, It is often seen as linked to the quest to turn lead or another common starting material into gold. An alchemist was called a 'chemist' in popular speech, and later the suffix "-RY " was added to this to describe the art of the chemist as "chemistry". Traditional chemistry starts with the study of elementary particles, atoms, molecules, Substances, Metals, Crystals and other aggregates of matter. A chemical reaction is a transformation of some substances into one or more different substances. Scientists engaged in chemical research are known as chemists. The standard nomenclature of compounds is set by the International Union of Pure and Applied Chemistry. (IUPAC) Carbon dioxide (CO2) an example of a chemical compound. A ball-and-stick representation of the caffeine molecule (C8H10N4O2). A chemical substance is a kind of matter with a definite Composition and Set of Properties. A collection of substances is called a mixture. Examples of mixtures are air and alloys. In the Methane molecule (CH4),Chemistry is typically divided into several major sub-disciplines.
There are also several main cross-disciplinary and more specialized fields of chemistry. The history of chemistry is intertwined with the history of thermodynamics, especially through the work of Willard Gibbs. Hydrogen bromide exists in the gas phase as a diatomic molecule. An animation of the process of ionic bonding between sodium (Na) and chlorine (C) to form sodium chloride, or common table salt in the physical sciences, a phase is a region of space, throughout which all physical properties of a material are essentially uniform. A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another REDOX. IS a type of chemical reaction in which the oxidation states of atoms are Changed. Physical chemistry is the study of the physical and fundamental basis of chemical systems and processes. In particular, the ENERGETICS and dynamics of such systems and processes are of interest to physical chemists. Chemistry classes, Mr. Vinod Kumar has 23 years experience in chemistry subjects.
