Development of the table of chemical elements

The periodic table is an arrangement of the chemical elements, structured by their atomic number, electron configuration and recurring chemical properties.

In the basic form, elements are presented in order of increasing atomic number, in the reading sequence.

How many elements were on the first periodic table

How did dmitri mendeleev organize the periodic table

Then, rows and columns are created by starting new rows and inserting blank cells, so that rows (periods) and columns (groups) show elements with recurring properties (called periodicity). For example, all elements in group (column) 18 are noble gases that are largely—though not completely—unreactive.

The history of the periodic table reflects over two centuries of growth in the understanding of the chemical and physical properties of the elements, with major contributions made by Antoine-Laurent de Lavoisier, Johann Wolfgang Döbereiner, John Newlands, Julius Lothar Meyer, Dmitri Mendeleev, Glenn T.
