Question
What is the need for classification of elements?
✓

Answer

It is impossible for a chemist to study all the elements and their compounds. Hence, classification is a must.
Following are the reasons for the classification of elements:
  • To study elements better
  • To correlate the properties of the elements with some fundamental properties which are characteristic of all the elements
  • To reveal relationships between elements
