Mendeleev's periodic table gained wide acceptance with the scientific community and earned him credit as the discoverer of the periodic law. Element number 101, synthesized in 1955, is named mendelevium after the founder of the periodic table. It was, however, several years after Mendeleev died before the several discrepancies with the atomic.

Dmitri Mendeleev First Periodic Table / Dmitri Mendeleev And A Brief History Of The Periodic
In Mendeleev's periodic table, elements were arranged on the basis of the fundamental property, atomic mass, and chemical properties. During Mendeleev's work, only 63 elements were known. After studying the properties of every element, Mendeleev found that the properties of elements were related to atomic mass in a periodic way.

The groups in Mendeleev's table are determined by how many oxygen or hydrogen atoms are needed to form compounds with each element. For example, in Group I, two atoms of hydrogen, lithium, Li, sodium, Na, and potassium form compounds with one atom of oxygen. In Group VII, one atom of fluorine, F, chlorine, Cl, and bromine, Br, react with one.

The Periodic System now showed its power and flexibility. It allowed the incorporation of these new mysterious gaseous elements as Group 0, after Group VII, the halogens, and before Group I. This is shown in Fig 3, a Table from the 1905 edition of Mendeleev's textbook, Osnovy ximii.3. The Group of inert gases is nicely separated to the left.
