Chemical Nomenclature
A CHEMICAL NOMENCLATURE is a set of rules to generate systematic names for chemical compounds . The nomenclature used most frequently worldwide is the one created and developed by the International Union of Pure and Applied Chemistry (IUPAC). The IUPAC's rules for naming organic and inorganic compounds are contained in two publications, known as the _Blue Book _ and the _Red Book _, respectively. A third publication, known as the _Green Book _, describes the recommendations for the use of symbols for physical quantities (in association with the IUPAP ), while a fourth, the _Gold Book _, contains the definitions of a large number of technical terms used in chemistry. Similar compendia exist for biochemistry (the _White Book_, in association with the IUBMB ), analytical chemistry (the _Orange Book _), macromolecular chemistry (the _Purple Book_) and clinical chemistry (the _Silver Book_)

Systematic Name
A SYSTEMATIC NAME is a name given in a systematic way to one unique group, organism, object or chemical substance , out of a specific population or collection. Systematic names are usually part of a nomenclature . A SEMISYSTEMATIC NAME or SEMITRIVIAL NAME is a name that has at least one systematic part and at least one trivial part. Creating systematic names can be as simple as assigning a prefix or a number to each object (in which case they are a type of numbering scheme ), or as complex as encoding the complete structure of the object in the name. Many systems combine some information about the named object with an extra sequence number to make it into a unique identifier . Systematic names often co-exist with earlier common names assigned before the creation of any systematic naming system. For example, many common chemicals are still referred to by their common or trivial names, even by chemists

Chemical Compound
A CHEMICAL COMPOUND (or just COMPOUND if used in the context of chemistry ) is an entity consisting of two or more atoms , at least two from different chemical elements , which associate via chemical bonds . There are four types of compounds, depending on how the constituent atoms are held together: molecules held together by covalent bonds , ionic compounds held together by ionic bonds , intermetallic compounds held together by metallic bonds , and certain complexes held together by coordinate covalent bonds . Many chemical compounds have a unique numerical identifier assigned by the Chemical Abstracts Service (CAS): its CAS number . A chemical formula is a way of expressing information about the proportions of atoms that constitute a particular chemical compound, using the standard abbreviations for the chemical elements, and subscripts to indicate the number of atoms involved

Organic Compound
An ORGANIC COMPOUND is virtually any chemical compound that contains carbon , although a consensus definition remains elusive and likely arbitrary. Organic compounds are rare terrestrially, but of central importance because all known life is based on organic compounds. The most basic petrochemicals are considered the building blocks of organic chemistry .

Inorganic Compound
A chemical compound is termed INORGANIC if it fulfills one or more of the following criteria: * There is an absence of carbon in its composition * It is of a non-biologic origin * It cannot be found or incorporated into a living organismThere is no clear or universally agreed-upon distinction between organic and inorganic compounds. Organic chemists traditionally and generally refer to any molecule containing carbon as an organic compound and by default this means that inorganic chemistry deals with molecules lacking carbon

Symbol
A SYMBOL is a mark, sign, or word that indicates, signifies, or is understood as representing an idea, object, or relationship. Symbols allow people to go beyond what is known or seen by creating linkages between otherwise very different concepts and experiences. All communication (and data processing) is achieved through the use of symbols. Symbols take the form of words, sounds, gestures, ideas or visual images and are used to convey other ideas and beliefs. For example, a red octagon may be a symbol for "STOP". On a map, a blue line might represent a river. Numerals are symbols for numbers . Alphabetic letters may be symbols for sounds. Personal names are symbols representing individuals. A red rose may symbolize love and compassion. The variable 'x', in a mathematical equation, may symbolize the position of a particle in space

Physical Quantity
A PHYSICAL QUANTITY is a physical property of a phenomenon , body, or substance, that can be quantified by measurement . A physical quantity can be expressed as the combination of a magnitude expressed by a number – usually a real number – and a unit ; for example, 6973167492749999999♠1.6749275×10−27 kg (the mass of the neutron ), or 7008299792458000000♠299792458 metres per second (the speed of light ). Physical quantities are measured as n u {textstyle nu} _ where n {textstyle n} is the magnitude and u {textstyle u} is the unit. For example: A boy has measured the length of a room as 3 m. Here 3 is magnitude and m (metre) is the unit. 3 m can also be written as 300 cm. The same physical quantity x {textstyle x} can be represented equivalently in many unit systems, i.e._ x = n 1 u 1 = n 2 u 2 {textstyle x=n_{1}u_{1}=n_{2}u_{2}}

Biochemistry
BIOCHEMISTRY, sometimes called BIOLOGICAL CHEMISTRY, is the study of chemical processes within and relating to living organisms . By controlling information flow through biochemical signaling and the flow of chemical energy through metabolism , biochemical processes give rise to the complexity of life . Over the last decades of the 20th century, biochemistry has become so successful at explaining living processes that now almost all areas of the life sciences from botany to medicine to genetics are engaged in biochemical research. Today, the main focus of pure biochemistry is on understanding how biological molecules give rise to the processes that occur within living cells , which in turn relates greatly to the study and understanding of tissues , organs , and whole organisms —that is, all of biology

Analytical Chemistry
ANALYTICAL CHEMISTRY studies and uses instruments and methods used to separate , identify, and quantify matter. In practice separation, identification or quantification may constitute the entire analysis or be combined with another method. Separation isolates analytes . Qualitative analysis identifies analytes, while quantitative analysis determines the numerical amount or concentration. Analytical chemistry
Analytical chemistry
consists of classical, wet chemical methods and modern, instrumental methods . Classical qualitative methods use separations such as precipitation , extraction , and distillation . Identification may be based on differences in color, odor, melting point, boiling point, radioactivity or reactivity. Classical quantitative analysis uses mass or volume changes to quantify amount. Instrumental methods may be used to separate samples using chromatography , electrophoresis or field flow fractionation
