Mendeleev
Hydrogen is the first chemical element in the Periodic Table of Mendeleev.
The first periodic table of elements was created by Dmitri Mendeleev, a Russian chemist, in 1869. He arranged the elements in order of increasing atomic weight and grouped them based on similar properties, leading to the development of the modern periodic table.
Mendeleev's periodic table was organized in order of increasing atomic masses. He arranged elements having similar properties together.
Both arrange elements in groups of elements having similar properties.
Both arrange elements in groups of elements having similar properties.
Dmitri Mendeleev in 1869
The first periodic table arranged by atomic mass was created by Dmitri Mendeleev in 1869. Mendeleev's periodic table organized elements by increasing atomic mass and grouped them based on similar chemical properties.
Mendeleev created a new row on the periodic table every time chemical properties were repeated.
The M periodic table, or Mendeleev's periodic table, is a historical version of the periodic table created by Dmitri Mendeleev in 1869. It organized elements based on their atomic mass and properties, leading to the prediction of undiscovered elements. Mendeleev's table highlighted periodic trends and allowed for the arrangement of elements into groups with similar characteristics. While modern periodic tables are organized by atomic number, Mendeleev's work laid the foundation for the development of the periodic table as we know it today.

Dmitri Mendeleev created the first periodic table of elements in 1869. He arranged elements by increasing atomic weight and grouped those with similar properties together. Mendeleev left gaps for undiscovered elements and was able to predict the properties of these missing elements.
