In this chapter, you will be introduced to the periodic table. You will learn the groups of elements within the periodic table that have similar properties. Periodic trends for properties such as atomic radius, ionic size, ionization energy, electron affinity, and electronegativity will be described.

In this chapter, you will learn: to state the periodic law to discuss the development of the periodic table to explain why elements in a group have similar properties to identify the four blocks of the periodic table to identify periodic trends and explain how trends reflect the electron configurations of the elements
