Chemical elements arrangement was the object of study for Mendeleev.
Dmitri Mendeleev developed the first periodic table of the elements.
Ga, Sc and Ge were important to Mendeleev because these three elements have the same physical and chemical properties.
mendeleev's name for a column of elements was groups.
what did Mendeleev see that elements it into
Dmitri Ivanovich Mendeleev was a Russian chemist and inventor. He is credited as being the creator of the first version of the periodic table of elements. Using the table, he predicted the properties of elements yet to be discovered.
The most important principle was the listing in groups, after similar chemical or physical properties.
He formulated the Periodic Law and revised and predicted the Periodic Table of Elements in some important ways.
Mendeleev arranged the elements according to their atomic weight and valence.
Independently by Dmitri Mendeleev and Lothar Meyer in 1869
to classify the elements mendeleev arranged the elements in increasing order of their atomic mass
Mendeleev arranged the elements in the increasing order of their atomic masses and repeating properties.
The atomic theory that was supported by Mendeleev when scientist found the elements that Mendeleev predicted was out there in the world. When Mendeleev made the periodic table he left spots for elements he did not have but knew would be found one day.
