Three-center two-electron bond — A three center two electron bond is an electron deficient chemical bond where three atoms share two electrons. The combination of three atomic orbitals form three molecular orbitals: one bonding, one non bonding, and one anti bonding. The two… … Wikipedia
Four-center two-electron bond — A four center two electron bond is a type of chemical bond in which four atoms share two electrons in bonding which is unusual because in ordinary chemical bonds two atoms share two electrons (2c 2e bonding). This type of bonding is postulated in … Wikipedia
Three-center four-electron bond — The 3 center 4 electron bond is a model used to explain bonding in hypervalent molecules such as phosphorus pentafluoride, sulfur hexafluoride, the xenon fluorides, and the hydrogen difluoride ion. [Greenwood Earnshaw p. 897.] [Weinhold, F.;… … Wikipedia
Three-center bond — In chemistry, there are two types of three center bonds: *Three center two electron bond, found in electron deficient compounds such as boranes *Three center four electron bond, found in hypervalent compounds such as the noble gas compounds … Wikipedia
Bent bond — Bent bond, also known as banana bond, is a term in organic chemistry that refers to a type of covalent chemical bond with a geometry somewhat reminiscent of a banana. The term itself is a general representation of electron density or… … Wikipedia
banana bond — noun An extended covalent bond found in boranes in which a hydrogen atom is shared by two boron atoms; a form of three center two electron bond … Wiktionary
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

Hydrogen bond — A hydrogen bond results from a dipole dipole force between an electronegative atom and a hydrogen atom bonded to nitrogen, oxygen or fluorine (thus the name hydrogen bond , which must not be confused with a covalent bond to hydrogen). The energy… … Wikipedia
Electron — For other uses, see Electron (disambiguation). Electron Experiments with a Crookes tube first demonstrated the particle nature of electrons. In this illustration, the profile of the cross shaped target is projected against the tube face at right… … Wikipedia
