What is Periodic Table?

Periodic Table Definition

The periodic table is an arrangement of the chemical elements, ordered by their atomic number (number of protons), electron configurations, and chemical properties. It was first published by the chemist Dmitri Mendeleev in 1869. At present the Periodic table has 118 elements.

Elements from atomic numbers 1 (Hydrogen) to 118 (Oganesson) have been discovered or synthesized. First 94 elements exist in naturally. Elements with atomic numbers from 95 to 118 have only been synthesized in laboratories or nuclear reactors.

How do you read the Periodic Table?

The Periodic Table covers all 118 elements. How to understand periodic table easily, let us know how the table is understand. The Periodic Table is designed in such a way that it becomes easy to understand for everyone to read and learn

Each row on the Periodic table is called a period and Each column on the table is called a group.

Elements in a period have the same number of orbitals, starting from one orbital at the top row, to seven orbitals at the bottom row of the Periodic table. We see an increase of one orbital in each row. Elements in the same period have the similar physical properties.

Elements in each group of Periodic table have the same number of electrons in the outer shell. Elements in the same group react similarly with other elements.

What are the current Changes in the Periodic Table?

Lastly 4 new elements Nihonium, Moscovium, Tennessine and Oganesson were added to the periodic table. This addition was approved by the International Union of Pure and Applied Chemistry (IUPAC) on 30th December, 2015 and officially named on November 28, 2016. The atomic number of these recently added elements are 113, 115, 117 and 118.

How many elements are there in Periodic Table?

At present the Periodic table has 118 elements. Elements arranged according to atomic numbers from 1 to 118. The first 94 elements existing in nature, Rest of the elements with atomic numbers from 95 to 118 have only been synthesized in laboratories.
