Honors Chemistry - Unit 7 Objectives (Part I)
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. Use the concept of
ionization energy along with
atomic radius to predict
reactivity within a given
period or group for both
metals and nonmetals.

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.
Use electronegativity values
to predict bond types
between atoms that are
covalently bonded.
8. Draw electron-dot
diagrams of for ionic and
molecular compounds.
