SCIENCE Chemistry

Lewis structures are also known as electron dot structures. The diagrams are
named for Gilbert N. Lewis, who described them in 1916. Lewis structures depict
the bonds between atoms of a molecule as well as any unbonded electron pairs.
You can draw a Lewis dot structure for any covalent molecule or ionic bond. Lewis
dot structures deal only with valence electrons.
IONIC BONDING with LEWIS DOT STRUCTURES
Step 1: Write the atomic symbol for the atoms involved.
Step 2: Pick a separate color skittles for each atom involved
Step 3: Ionic bonds – lay out the electrons to be donated and show where they
go with an arrow.
Step 4: Show the final ions as positive and negative.
Make the following bonds and be able to explain what you did.
Ionic –
