Modern Periodic Table 5.2

Modern Periodic Table 5.2. The Periodic Law. In the modern periodic table, elements are arranged by increasing atomic number (number of protons) Properties of elements repeat in a predictable way when atomic numbers are used to arrange elements into groups. This is called periodic law.
