The periodic table is like a map that organizes elements based on their atomic structure and properties. It helps scientists and students study and understand the vast variety of elements and how they ...

Elements in the same horizontal row are in the same period. The periods are numbered from top to bottom. The period number is the same as the number of occupied electron shells.

The periodic table is not just the story of discoveries aided by better technological innovations, it’s also the story of sheer genius The National Council of Educational Research and Training (NCERT) ...
