Modern Periodic Table

Definition - What does Modern Periodic Table mean?

Modern Periodic Table, also known as the Periodic Table, is a tabular arrangement in which chemical elements are arranged according to their atomic numbers, configuration of electrons and chemical properties. A Modern Periodic Table consists of four block, i.e., the “S”, “P”, “D” and “F” blocks. Metallic elements are located on the left hand side of the Modern Periodic Table, whereas non-metallic elements are located on the right hand side.

Petropedia explains Modern Periodic Table

The Modern Periodic Table is based on Moseley’s Periodic Law. According to this law, the properties of the elements listed in the periodic table are periodic functions of their atomic numbers. Therefore, if the elements in a periodic table are arranged in the order of their increasing atomic numbers, then the elements which have similar properties will be repeated in a regular interval. The atomic number of an element mentioned in the periodic table is equal to the number of protons in its atom nuclei.
