What is compound?
The word compound comes from the Latin composĭtus, we can talk about something being “composed of” to indicate what things make up something , and in the matter of chemistry , a compound is a substance that is formed by two elements of the periodic table or still plus.
The compounds have a chemical formula . A compound is made up of molecules or ions that have a certain charge (positive in the case of protons or negative in that of electrons ) and bonds . The elements that make up a compound cannot be separated with any physical treatment or process, but only with a chemical one. To name a case, we can give as an example hydrofluoric acid, which is composed of a fluorine atom and a hydrogen atom.
In inorganic chemistry the compounds are represented by chemical symbols. They are classified into organic and inorganic compounds and these are: acidic oxides (formed by a metal and oxygen), basic oxides (formed by a nonmetal and oxygen), hydrides (a metallic element or not and hydrogen), hydrazides (nonmetals, when dissolved in waterit becomes acidic), hydroxides (formed by the reaction of a basic oxide and water), oxyacids (composed of the reaction of an acidic oxide and water), binary salts (it is a hydrocide plus a hydroxide), oxysal (composed of reaction of an oxyacid and a hydroxide), aliphatic compounds (consisting of carbon and also non-aromatic hydrogen), aromatic compounds (cyclic organic compound conjugated with greater stability), heterocyclic compounds (cyclic organic compound; at least one of the components is of a non-carbon element), organometallic compounds ( carbon atoms form covalent bonds ) and polymers (macromolecules formed by the union of smaller molecules).
It is important that a distinction be made between a compound and between a mixture or alloy. The mixture has elements that can be identified or separated very easily; The alloy consists of two or more elements of which at least one is a metal.

- Grammar : The term compound is used because it is a word that is created with the composition of two simple terms. For example “please Javier, pass me the remote control”. In this case “remote-control” would be the compound word.
- Botany : There is talk of compound plants, which are those that have simple leaves and flowers grouped in a common receptacle.
- Economy : The compound interest is the money, profit or the utility of aninitial capital at an interest rate during a certain period of time in which at the end of the generated interest they are reinvested.
