Types of Compounds
A compound is defined as a pure substance formed when two or more elements chemically combine in a fixed ratio. Unlike elements, compounds exhibit distinct properties that are different from those of the individual elements that compose them. This section outlines the characteristics of compounds, detailing how they can only be separated through chemical reactions, unlike mixtures, which can be separated using physical methods. Compounds can be classified into two main categories: organic and inorganic. Organic compounds primarily contain carbon, exemplified by substances like glucose and methane, while inorganic compounds may not contain carbon, such as common salt and water. Understanding the distinctions between compounds and mixtures is vital in chemistry as these differences play a crucial role in various scientific applications.
