Covalent radius — Types of radii Atomic radius Ionic radius Covalent radius Metallic radius Van der Waals radius edit The covalent radius, rcov, is a measure of the size of an atom that forms part of one covalent bond. It is usually measured either in … Wikipedia
Covalent radius of fluorine — The covalent radius of fluorine is a measure of the size of a fluorine atom; it is approximated at about 60 picometres. Since fluorine is a relatively small atom with a large electronegativity, its covalent radius is difficult to evaluate. The… … Wikipedia
Chemical bond — A chemical bond is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms. The bond is caused by the electromagnetic force attraction between opposite charges, either between electrons and… … Wikipedia
