Here, periodic classification is re-introduced. In this video, students learn about the order in which electrons fill their shells, and the proper roman numeral classification of groups and periods.

Learning Goals:

To describe the periodic table as a structured classification of elements
To be able to determine the number of valence electrons in an element
