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

Atomic radius — Diagram of a helium atom, showing the electron probability density as shades of gray. The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the nucleus to the boundary of the… … Wikipedia
Ковалентный радиус — в химии это половина расстояния между ядрами атомов данного элемента, образующими ковалентную связь. За величину ковалентного радиуса принимается половина кратчайшего межатомного расстояния в кристалле простого вещества. Другими словами,… … Википедия
Bond length — In molecular geometry, bond length or bond distance is the average distance between nuclei of two bonded atoms in a molecule. Explanation Bond length is inversely related to bond order, when more electrons participate in bond formation the bond… … Wikipedia
Bond energy — In chemistry, bond energy ( E ) is a measure of bond strength in a chemical bond. For example the carbon hydrogen bond energy in methane E (C–H) is the enthalpy change involved with breaking up one molecule of methane into a carbon atom and 4… … Wikipedia
