What is a Chemical Compound?
A chemical compound is a type of molecule (collection of bonded atoms) made up of more than one element. For instance, water (H2O) is a compound, whereas diatomic hydrogen (H2) is not. Most of the atoms that make up the Earth’s crust and living organisms are in compound form. Compounds are represented by molecular formulae which list the constituent atoms and their abundance. Depending on the atoms, a compound may be held together by different chemical bonds. Bonds are formed through the interactions of atomic electron shells in various orbital configurations. Depending on the number of electrons orbiting the nucleus of the atom and the amount of space in the orbitals, certain atoms are prone to bonding with certain other types of atoms. Lewis dots, a graphical system of representing compound bond types, named after the chemist Gilbert Lewis, is often taught in High School chemistry classes. The existence of chemical bonds has been speculated about since at least the 12th century, alth
Compounds are substances that are two or more elements combined together chemically in a standard proportion by weight. Compounds are all around us – they include familiar things, such as water, and more esoteric substances, such as triuranium octaoxide, the most commonly occurring natural source for uranium. This reference guide gives us a tour of 100 of the most important, common, unusual, and intriguing compounds known to science. Each entry gives an extensive explanation of the composition, molecular formula, and chemical properties of the compound. In addition, each entry reviews the relevant chemistry, history, and uses of the compound, with discussions of the origin of the compound’s name, the discovery or first synthesis of the compound, production statistics, and uses of the compound.
