GENERAL CHEMISTRY 101
PERIODICITY
The importance and usefulness of the periodic table lie in the fact that
we can use our understanding of the general properties and trends within a
group or a period to predict with considerable accuracy the properties of
any element, even though that element may be unfamiliar to us. We
continue this topic with a discussion of the periodicity of the elements..
..(see
syllabus). Its important that you complete the ....
"self-
.......exercises in each section!)
Development of the Periodic Table
•Glossary
VISUALIZATION: Periodicity

......and more.......
•Test 1
•Test 2
•Test 3(collection)
Concurrently you should review the appropriate 
rea(s)
as needed.
In addition to the regular homework assignments of problems from the text,
self paced exercises, activities, quizzes, and virtual/practicals are
incorporated in each major section of this course. It is important, to
the extent possible, that each student take maximum advantage of these
study aids!
