C2.1 development of the periodic table
WebDevelopment of the Periodic Table. The periodic table is a chart that reflects the periodic recurrence of chemical and physical properties of the elements when the elements are arranged in order of increasing atomic number(the number of protons in the nucleus). It is a monumental scientific achievement, and its development illustrates the ...
