Mendeleev Periodic Table
In order to represent similarities and trends in the behavior of elements, Mendeleev developed the periodic table, which is an arrangement of elements in an increasing atomic mass order in tabular form.
According to Mendeleev’s Periodic Table, elements were arranged as per their fundamental property, atomic mass, and chemical characteristics. Only 63 elements were known at the time of Mendeleev’s work. In the Mendeleev periodic table, the horizontal row and vertical columns were referred to as groups and periods, respectively.
However, Mendeleev’s Periodic Table fails due to many flaws in it. Some of them are, that it failed to designate Hydrogen and Noble gases in it. Also, the increasing order of the atomic mass of the elements wasn’t regular throughout the table. Even, the discovery of isotopes violates the Mendeleev Periodic Law.

Periodic Table of Elements
The Periodic table of elements is a systematic arrangement of 118 known chemical elements. These chemical elements are organized in order of increasing atomic number. The horizontal rows from left to right are called periods while the vertical columns from top to bottom are called groups in a periodic table.
