What Is The Periodic Table & Its Importance

Periodic Table of elements is the table in which all the chemical elements that are known to mankind are arranged in a proper order. The order is the recurring chemical properties, increasing the order of an element’s atomic number and configuration of an electron. A periodic table is considered as the significant tool in the history of chemical science.

It defines the atomic property of the element. Elements with the same chemical properties are put up in columns of the periodic table. It defines the structure of atoms of all elements. For instance, we can find out that how many electrons the element possesses and what is the weight of those electrons just by looking at the periodic table. Each chemical element has its own unique set of such data and no elements are the same.

Therefore, if you are someone who is uncertain what matter they have, they just can easily look at the structure of atoms of that element and can compare it to the data of the periodic table and then identify the element by matching to the element in a table with the same kind data. Elements in the periodic table are divided into different periods and families. The elements in every family and period may have similar non-similar features.

What Is a Period in the Periodic Table

Horizontal rows in the periodic table are called periods. Chemical elements in the same row have the same number of a shell of an electron. Every next element in a period of a periodic table has one more no. of proton and is less metallic than the prior element. Elements that are in the similar column has the same physical and chemical properties and this reflects the periodic law.
