In this video, we will learn about the periodic table through its history and structure. A very important tool in Chemistry, the periodic table will be studied in two videos, this one about its history and structure and the second one about its periodic properties. This one will introduce the Father of the table (Mendeleev) as well as the concept of metals and nonmetals, noble gases, families, periods, series, etc. We will learn how to do an electronic reading of this magnificent tool too!
