In the first Periodic Table by Mendeleev, he arranged the elements in the increasing order of their atomic masses and repeating properties.
Dmitri Mendeleev arranged the elements in his periodic table based on their atomic masses and chemical properties. He left gaps for undiscovered elements and predicted their properties accurately.
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.
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.
The reason the periodic table was created in the first place was to illustrate the "periodic" physical properties of the known elements of the time. Because of this, the properties of elements that were "missing" from the table could be extrapolated from the periodic trends seen in the known elements.

Mendeleev developed the first periodic table and Mosely later modernized it.
Dmitri Mendeleev, a Russian chemist, was the first to notice that the properties of elements seemed to repeat periodically when arranged in order of increasing atomic mass. He created the first version of the periodic table based on this observation in 1869.
the properties of a compound are not the same as the elements that form them.

The properties of the compound will differ from the properties of the elements of which it is made.
