Question

Why do we need to group materials? Give one reason.

Answer 1

Hint: In order to solve the given problem we will first see the reasons behind the grouping of different materials. We will also understand the basic concept and the characteristics required for classification of materials and also with the help of some examples try to understand the practical use of a group of materials.

Complete step by step solution: There are a lot of materials and elements found in our environment some of them are natural and some others are laboratory prepared. There are a lot of similarities and differences between each of them on the basis of several factors. But it is hard for anyone to study the structure, behaviour and properties of each one of them individually and also to remember them for chemical use. So for the convenience and to make the study of different materials easier and convenient we group the materials on the basis of different properties.
The grouping or the classification of materials makes the study easier and also saves our time and energy.
Periodic table is a perfect example of this grouping. Different elements are kept in rows and columns on the basis of their chemical properties and behaviour.
The modern periodic table has been developed after a lot of development and modification by different scientists on a regular basis.

Note: In order to solve such types of problems students must be aware of different groups formed in the periodic table and on the general basis should know the group of elements. Students may make a group of materials on their own but only if the characteristics of the elements are similar to each other. The periodic table is a tabulated collection of atomic number-organized chemical elements from the element with the lowest atomic number, hydrogen, to the element with the largest atomic number .
