In 1869, a total of 63 elements had been discovered by. A few were gases. Two were liquids. Most were solid metals.
Dmitri Mendeleev discovered scandium, gallium, technetium, and germanium. He also predicted the existence of more elements and developed the modern Periodic Table.
He proposed his periodic table, where he arranged the elements in the increasing order of atomic weights and repeating properties.
Periodic Table of Elements
Dmitri Ivanovich Mendeleyev. Another spelling of his name is Dmitri Ivanovich Mendeleev.
he drew up a table that grouped elements according to their atomic weights, his table became the basis for the periodic table of elements used today.
It is named after Dmitri Mendeleev, the scientist who was responsible for devising the periodic table of elements.
He invented the periodic table. You must know what that means; he was the father of basic chemistry. Actually, he didn't discover the periodic table. He just arranged the only elements he had available in his day (not a lot) and arranged them based on patterns of # of protons, electrons, reactivity, etc. He didn't have an in-depth knowledge yet of electron configuration ;however, his "guess" turned out to have so many great implications that we now use his invention everyday everywhere.
He focused on the Periodic Table
gallion,silicon and gold
Dmitri Mendeleev published his periodic table in 1869.
63 elements were in Dmitri Mendeleev's First periodic table 63 elements were in Dmitri Mendeleev's First periodic table
Independently by Dmitri Mendeleev and Lothar Meyer in 1869
Dmitri mendeleev arranged elements in order of increasing atomic masses. He considered chemical properties of the elements, their oxides and nitrides.
Dmitri Mendeleev performed his research during the year 1847.
Dmitri Ivanovich Mendeleyev. Another spelling of his name is Dmitri Ivanovich Mendeleev.
Dmitri Mendeleev is credited with being the first scientist to arrange and classify elements into a chart. He was a Russian chemist who lived from 1834 to 1907.
