Periodicity and Bonding
Learning objectives:
What we did to meet the
objective (include date of
the lesson):
What I learned (include sketches of apparatus,
graphs, particle diagrams, and sample problems,
etc., as appropriate) :
Anything else? (Example,
non-example, important
steps, or pitfalls, etc.)
1. Define ionization energy;
indicate the general trend in
ionization energies
with increasing atomic
number:
a. within a given row
b. within a given family
of elements
2. Define atomic radius;
indicate the general trend in
atomic radius with
increasing atomic number:
a. within a given row
b. within a given family
of elements

3. Demonstrate your
understanding of the
concept of grouping of
elements in terms of similar
chemical properties; state
the general characteristics
of four major families: the
alkali metals, the alkaline
earth metals, the halogens
and the noble gases
4. Explain the behavior of
elements in a given family
in terms of their tendency to
achieve a noble gas electron
arrangement by gaining or
losing electrons.
5. Draw Lewis Dot
Structures of valence
electrons for the
Representative Elements.

6. Using the Periodic Table,
predict the formula of the
compound formed by a given
pair of elements.
7. Describe the conditions
that make a chemical bond
primarily covalent or ionic.
8. Draw electron-dot
diagrams (Lewis Dot
Structures) of for ionic and
molecular compounds.
9. Recognize that ionic
compounds have ionic bonds
and molecular compounds
have covalent bonds.
Distinguish between what
an ionic bond and covalent
bond mean in terms of
electrons.
