Periodic Table

What is the Periodic Table?

The periodic table organizes all known elements in order of increasing atomic number and recurring chemical properties. They are arranged in a tabular format, with a row representing an era and a column representing a group.

Elements are ordered in increasing atomic number from left to right and top to bottom. Thus,

• Elements in the same group will have comparable chemical characteristics since they have the same valence electron configuration.
• Elements in the same period, on the other hand, will have an increasing order of valence electrons. As a result, as the atom’s energy level rises, so does the number of energy sub-levels per energy level.

The first 94 elements of the periodic table occur naturally, but the remaining elements from 95 to 118 have only been created in laboratories or nuclear reactors.

The contemporary periodic table, which we presently use, is a revised and enhanced version of certain models proposed by scientists in the nineteenth and twentieth centuries. Dimitri Mendeleev proposed his periodic table based on the discoveries of previous scientists such as John Newlands and Antoine-Laurent de Lavoisier. Mendeleev, on the other hand, is awarded sole credit for developing the periodic table.

Mendeleev Periodic Table

Dimitri Mendeleev, usually regarded as the father of the periodic table, proposed the initial iteration of the periodic table, which is still in use today. Mendeleev’s periodic law differs from contemporary periodic law in one important way.

• Mendeleev based his periodic table on increasing atomic mass, but modern periodic law is based on increasing atomic number order.

Mendeleev’s periodic chart, despite being based on atomic weight, was able to predict the discovery and qualities of certain elements. Only roughly half of the elements known to us now were known during his time, and much of the information known about the elements was incorrect. Mendeleev’s Periodic Table was first published in 1869 in the German Journal of Chemistry.
