In order to represent similarities and trends in the behavior of elements, Mendeleev developed the periodic table, which is an arrangement of elements in an increasing atomic mass order in tabular form.Īccording to Mendeleev’s Periodic Table, elements were arranged as per their fundamental property, atomic mass, and chemical characteristics. The Mendeleev periodic table was the most important of many periodic tables like the Newlands Octave Law that was rejected in 1869. Russian scientist Dmitri Ivanovich Mendeléev made the most significant contribution to the early creation of the periodic table. The elements listed are arranged according to the increasing order of atomic number and their respective atomic weight, symbols, density, and electronegativity. Here is the table representing 118 elements of the periodic table. Such elements are present in Lanthanides and Actinides groups. f-block elements: These elements have the last electron filled in their f-subshell. ![]() d-block elements are also called transition elements as they have partially filled d-orbitals in their ground state. These elements have the last electron filled in their d-subshell.
