Why Lesson Planet?
Thorough explanations of the trends in the periodic table of elements make up the majority of this handout. Atomic and ionic size, ionization energy, electron affinity, and electronegativity are presented before giving chemistry candidates a shot at three related exercises. Answers are printed right below the practice problems, so this is best used as a learning tool. Note: Although there is a textbook reference, the handout is valuable even if you do not use the same particular text.
