Periodic Trends
... Trend: a general or prevailing tendency. Every element does not need to follow the trend. Often the exceptions are as enlightening as the trend. The trends in a periodic table of the elements depend on the arrangement of elements in that table. Most of the focus in this class will be on the s- and p ...
