The Lewis structure indicates that each Cl atom has three pairs of electrons that are not used in bonding (called lone pairs) and one shared pair of electrons (written between the atoms). A dash (or line) is sometimes used to indicate a shared pair of electrons: Cl—Cl....

Because two equivalent Lewis structures can be written, NO2 is a resonance hybrid in which the N–O bond order is 1.5. More than one non-equivalent structure It sometimes happens that the octet rule can be satisfied by arranging the electrons in different ways. For example, there are ...
The covalent bond is drawn as a dash in a Lewis structure to distinguish the bonding pair from the lone pair electrons. Lewis structures show the nonbonding electrons as pairs of dots located about the atomic symbols for the atoms. The Lewis structures of four simple organic compounds—methane...

* The Lewis dot structure for H2molecule is shown below. Note that each hydrogen gets two electrons after forming the bond. The bond between two hydrogen atoms can be shown as a line, which represents a bond pair of electrons. Note: The bond between two hydrogen atoms is non polar since...
