What are the main features of the periodic classification of the elements?

Periodic classification of elements refer to the periodic table of elements in which elements have been arranged according to their atomic numbers and electronic configurations.


The periodic table of elements contain horizontal rows (known as periods) and vertical columns (known as groups). In all there are 7 periods and 18 groups in the periodic table. All the elements with similar electronic configuration are placed in the same vertical column or group. In a period, the atomic number of elements increases as we move from left to the right side of the periodic table. 


This classification ensures that we have some idea about the properties of an element by knowing its position in the table. There are also blank spaces in the periodic table for yet-to-be discovered elements. 


Thus, a periodic table of elements is very useful to students and scientists and anybody else who is working with elements.


Hope this helps.
