A CHEM Study film
Presents experimental evidence of the periodic nature of chemical elements and explains the development of the periodic table. Includes experiments to show the classification of chemicals. Compares the data obtained from the experiments with the periodic table; illustrates the key to discovering chemical families, and explains that atomic numbers are essential in the arrangement of the families on the periodic table
Explains how chemical similarities among the elements have provided th./ia metadata chemicalfaviding them into families. Explains how atomic numbers have provided the key to the ordering of the elements in the periodic table.
