Lothar Meyer's periodic table, published in "Die modernen Theorien der Chemie" (1864) [4] His book, Die modernen Theorien der Chemie , which he began writing in Breslau in 1862 and published two years later, contained an early version of the periodic table.

Dmitri Mendeleev published a periodic table of the chemical elements in 1869 based on properties that appeared with some regularity as he laid out the elements from lightest to heaviest. [1] When Mendeleev proposed his periodic table, he noted gaps in the table and predicted that then-unknown elements existed with properties appropriate to fill ...
Dmitri Ivanovich Mendeleev (/ ˌ m ɛ n d əl ˈ eɪ ə f / MEN-dəl-AY-əf; [2] [b] [a] 8 February [O.S. 27 January] 1834 – 2 February [O.S. 20 January] 1907) was a Russian chemist known for formulating the periodic law and creating a version of the periodic table of elements.
Mendeleev arranges the 63 elements known at that time (omitting terbium, as chemists were unsure of its existence, and helium, as it was not found on Earth) into the first modern periodic table and correctly predicts several others. 31 Gallium: 1875 P.

The periodic table, also known as the periodic table of the elements, is an ordered arrangement of the chemical elements into rows ("periods") and columns ("groups").
Hinrichs is one of the discoverers of the periodic laws, which are the basis for the periodic table of elements. [1] Although his contribution is not generally considered as important as those of Dmitri Mendeleev or Lothar Meyer, in 1867 (two years before Mendeleev) he presented his ideas on periodicity among the chemical elements in his privately printed book Programme der Atommechanik, [8 ...
Sample illustration: Periodic table in the style of a space lemniscate by William Crookes. In a self-published book, Types of Graphic Representation of the Periodic System of the Elements (1957) he listed some 700 images published since 1862, classified under 146 heads. [7]
