Johann grouped together Earth, Wind, and Fire as the first three elements.
Dobereiner was responsible for grouping element into triads. He grouped 3 element with same properties together.
Dmitri Mendeleev's first experimental effort in organizing elements into groups resulted in the periodic table of elements. His table arranged elements in order of increasing atomic mass, with elements exhibiting similar properties grouped together. This laid the foundation for our modern understanding of the periodicity of chemical elements.
The first attempt at listing elements on the periodic table was made by Dmitri Mendeleev in 1869. He arranged the elements in order of increasing atomic weight and grouped elements with similar properties together. Mendeleev's periodic table laid the foundation for the modern periodic table used today.
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.
Dmitri Mendeleev is credited with creating the first periodic table of elements in 1869 after noticing a recurring pattern of properties when arranging elements by atomic mass. Johann Wolfgang had no direct involvement in the discovery of the periodic table.

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.

Johann Wolfgang Döbereiner
In the first Periodic Table by Mendeleev, he arranged the elements in the increasing order of their atomic masses and repeating properties.
The first trends used to classify elements were atomic mass and chemical properties. The periodic table was originally arranged based on increasing atomic mass, where elements with similar chemical properties were grouped together. This led to the discovery of periodic patterns, eventually resulting in the modern periodic table organized by atomic number.

Hydrogen is the first chemical element in the Periodic Table of Mendeleev.
Mendeleev organized elements by their atomic mass and properties, arranging them in a table where elements with similar properties were grouped together. Gaps were left for undiscovered elements, allowing Mendeleev to predict the properties of these missing elements based on their position in the table. This led to the development of the first periodic table.

yes, he had 20 kids all together...7 with his first wife and 13 with his second wife.
