Lewis StructuresLewis symbols can be used to indicate the formation of covalent bonds, which are shown in Lewis structures, drawings that describe the bonding in molecules and polyatomic ions. For example, when two chlorine atoms form a chlorine molecule, they share one pair of electrons:...

A Lewis structure is a diagram that shows the covalent bonds and lone electron pairs in a molecule. Lewis structures are based on the octet rule. While Lewis structures are useful for describing chemical bonding, they are limited in that they do not account for aromaticity, nor do they accur...
* Thus Cl2molecule is formed with a covalent bond between two chlorine atoms. * In Cl2molecule, each Cl atom gets 8 electrons in its outer shell. See the diagram below. The bond pair is also shown as a line. The electron pairs which do not participate in the bonding are known as lone...
Draw Lewis structures for SeF_6 and include all-electron lone pairs. Is the octet rule satisfied in each case? Draw the best Lewis structure of [(CH3)3O]^+); fill in any nonbonding electrons. Calculate the formal cha...
Lewis Structures: Lewis structures are graphical representations of the bonding between atoms within a covalent compound. In order to draw a Lewis structure we must attempt to fill the octet of each of the constituent atoms while retaining the number of total valence atoms within the molecule. ...
