Bonding pair of electrons

from Wikipedia, the free encyclopedia
Methane (CH 4 ) in two-dimensional representation. The molecule contains four equivalent (covalent) C – H bonds between the central carbon atom and the four hydrogen atoms.
Methane in three-dimensional representation. The bond angles between the four covalent C – H bonds are each 109.5 °.

A bonding pair of electrons is a pair of electrons that lie between two atoms and thus form a covalent bond between the atoms. In valence line formulas , binding electron pairs are shown as a line between element symbols. In contrast to ionic bonds, covalent bonds are directional.

By sharing bonding electron pairs and, if necessary, non- bonding electron pairs , atoms can achieve the stable electron configuration of the noble gases ( noble gas configuration ).
