What is the modern periodic table?
The modern periodic table is the arrangement of all the known elements such that elements with similar characteristics are grouped. We know that the modern periodic table is made up of horizontal periods and vertical groups. In this article, we are going to study the similarities and periodicity of elements across the periodic table. We will study the different blocks: s-block, p-block, d-block, f-block and their characteristic properties, metals, metalloids, nonmetals, halogens, and noble gases.
