Answer 2

here are total of 118 element6 known so far and the discovery of new elements still continues. Every element has its own importance in the environment , some of them are useful while other are harmful. The harmful elements may also be useful in other way.

It becomes a necessity to study the chemical and physical properties of each of the elements present around us because every element is related to our lifein some or other way. As the number is very large and there is possibility that more elements will be discovered, so it becomes very difficult to study each of them separately. We need to classify them in some groups according to their properties so that we can study them in group more easily and effectively. Periodic table is the tool which is used to classify the known elements in groups

.It helps us to undertake a systematic study of the various elements found in nature without which it would have been impossible for us to study all the elementsin the table. With the help of periodic tablea comparative study of the elements and their compounds can be done.
