Mendeleev's Periodic Table

 A periodic table is one of the most important classifications of elements in chemistry for practical and theoretical applications. There were many geneses for the classification of elements and their positions on the periodic table. The most accepted one is Mendeleev periodic table.

Mendeleev Periodic Table

Dmitri Mendeleev designed the periodic table by arranging the elements in horizontal rows and vertical columns in the increasing order of their atomic weights in such a way that the elements with similar properties occupied the same vertical column or group. It’s an evolved version, a remarkable achievement for laying the foundation for the development of the modern periodic table.

In this periodic table, the elements were arranged into 7 horizontal rows known as periods and 8 vertical columns known as groups.

“The properties of the elements are a periodic function of their atomic weights”. This statement forms the basis of Mendeleev’s periodic table. The elements in Mendeleev’s periodic table are given below.
