Review the rules for drawing Lewis structures and try to draw the correct Lewis structures for the molecules shown in part A of this exercise.
Why is the ability to draw a Lewis structure considered a core chemistry skill?
Why is this theory successful? Can you name some of the limitations of the theory?

to determine the shape of the
molecule or ion
to determine the formulas of ionic
compounds
Lewis theory allows us
to account for the paramagnetism of
some species (e.g. oxygen)
to determine how the bonds in the
molecules and ions form
to predict what molecules or ions will
be stable, which will be more
reactive, and which will not exist
to account for the low melting points
and boiling points of molecular
compounds compared to ionic
compounds

Understanding the nature and types of chemical bonds is essential for explaining how substances interact and transform during chemical reactions. There are three primary types of chemical bonds: ionic, covalent, and metallic, each with distinct characteristics and significance.arrow_forward
