Deming’s table first appeared in his 1923 textbook General Chemistry and was slightly modified in each edition until the final one appeared in 1952. A 1923 Deming Periodic Table; chemists frequently credit Horace Deming, a professor at the University of Nebraska, with being the progenitor of the modern periodic table. The periodic table is a chart containing information about the atoms that make up all matter. An element is a substance made up of only one type of atom. The atomic number of an atom is equal to the number of protons in its nucleus. The periodic table we use today is based on the one devised and published by Dmitri Mendeleev in 1869. Mendeleev found he could arrange the 65 elements then known in a grid or table so that each element had: 1. A higher atomic weight than the one on its left. Periodic Table of Elements - The periodic table is a very useful listing of all 118 elements by symbol, atomic number, and atomic mass and molecular mass. Elements with similar chemical properties are called groups. Visit BYJUS to learn more about it. What is the Periodic Table? The periodic table is an arrangement of all the elements known to man in accordance with their increasing atomic number and recurring chemical properties. They are assorted in a tabular arrangement wherein a row is a period and a column is a group.

The periodic table of the chemical elements is a tabular method of displaying the chemical elements, first devised in 1869 by the Russian chemist Dimitri Mendeleev.

Mendeleev intended the table to illustrate recurring ('periodic') trends in the properties of the elements.

The layout of the table has been refined and extended over time, as many new elements have been discovered since Mendeleev's time, and new theoretical models have been developed to explain chemical behavior.

Various layouts are possible to emphasize different aspects of behavior; the most common forms, however, are still quite similar to Mendeleev's original design.

The main value of the periodic table is the ability to predict the chemical properties of an element based on its location on the table.

It should be noted that the properties vary differently when moving vertically along the columns of the table, than when moving horizontally along the rows.

The periodic table is now ubiquitous within the academic discipline of chemistry, providing an extremely useful framework to classify, systematize and compare all the many different forms of chemical behavior.

The table has also found wide application in physics, biology, engineering, and industry.
