Why is it important to have "alternate forms" of the periodic table?

so that you can see the different aspects of science

Explanation:

Alternate forms are useful because of the different aspects of the science that they illustrate - Carmen Giunta (a chemist at Le Moyne College in Syracuse, N.Y.)

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
