Ch 5 & 6.3: Chemical Bonding
and chemical reactions
Benchmarks and Indicators:
 Explain how atoms react with each other to form other substances and how
molecules react with each other or other atoms to form even different substances.
 Explain that the electric force between the nucleus and the electrons hold an
atom together. Relate that on a larger scale, electric forces hold solid and liquid
materials together (e.g., salt crystals and water.).
 Show how atoms may be bonded together by losing, gaining or sharing electrons
and that in a chemical reaction, the number, type of atoms and total mass must
be the same before and after the reaction (e.g., writing correct chemical formulas
and writing balanced chemical equations).

In this unit, we’ll be looking expanding on what we did in the last
about the periodic table. We’ll look at:
Patterns from the periodic table in terms of valence electrons and
resulting charges
Why/how elements bond together to make compounds and
molecules.
How the atoms’ families (metals, nonmetals or metalloids) affects
the kind of bond (ionic or covalent) that forms.
Naming of ionic and covalent compounds, including polyatomic ions
Writing a formula from the name of the compound, including
determining charges for transition metals.
Balancing chemical equations
For the test, you will have to draw Lewis diagrams for some
compounds (not just atoms). You should be able to correctly name the
compounds and tell whether they are ionic or covalent bonds. You
should be able to balance chemical equations, including writing the
formulas from the name. You will also have to answer some short answer
and/or multiple choice questions about how matter is constructed.
You will have a periodic table to help you out.
