Why was there a need for classification of elements ? Give atleast two reasons.

​

Answer 1

Answer:

$\huge{\underline{\underline{\boxed{\sf{\red{Answer ࿐}}}}}}$

It enables chemists to predict the properties of the elements and their compounds based on their positions in the Periodic Table, and vice versa. It becomes easier to study, understand, compare and contrast the related properties among the elements and their compounds from different groups.

• The continuous discovery of new elements and their compounds led to confusions.
• It became difficult to study, remember and recall the properties of all the elements.
• Thus, the need to classify and place them in certain groups was felt.
