A Lewis dot structure represents the bonding in a compound by showing the arrangement of outer shell electrons. It uses the symbols of the elements and dots to indicate valence electrons. To make a Lewis dot structure, write the symbols of the atoms and place them near each other. Then distribute the dots representing valence electrons between the atoms to show how they are shared or bonded to complete the outer electron shells. For example, a Lewis dot structure of water H2O shows two hydrogen atoms single bonded to an oxygen atom by sharing their single electrons.

2. WHAT IS A LEWIS DOT
STRUCTURE?
• A Lewis Dot Structure is an
easy way of representing a
compound.
• It consists of an element’s
symbol and dots to
represent valence electrons

3. HOW ARETHEY MADE?
• Write the symbol for each
atom involved. If you have
more than one of an
element, draw two symbols.
• The dots, or circles, around
them represent valence
electrons
• Any lines between two
atoms represent double
bonds.
• Arrange the atoms and the
valence electron shells are
within range of each other.
• Place the dots in the
appropriate places
