Atomic Lewis Diagrams
In covalent bonding, both atoms are trying to attract
electrons--the same electrons. Thus, the electrons are shared
tightly between the atoms. The force of attraction that each atom exerts on the
shared electrons is what holds the two atoms together.
|The shared electrons of a covalent bond can be
represented using Lewis diagrams. The bond can be emphasized by using a
line to "hold the atoms together." The electron dots that are not involved in
the bond are sometimes shown and sometimes not shown.
