Question

Ria and Reena are the students of Class X. Ria is very much organized and
maintained whereas Reena is an unorganised student and always faces a
lot of problems in handling life situations.
(a) How organization helps in daily life ?
(b) How can you relate the above fact with the chapter ‘Classification of
Elements’. How classification of elements help us studying them
properly ?

Answer 1

Organization helps us :
---> To save our time .
---> Work can be done systematically.
---> Queries related to our task can be asked.
---> Helps us to be neat and well maintained.
----> Gives us opportunity to study further about our things in future.
---> We can perform our task accurately.

In the same manner all the elements of the periodic table are classified in 18 groups and 7 periods.By this classification:

--> we can know about the valency of an element and  Its reactivity.
---> We can predict it is metal or non metal.
---> Helps us to further investigate and discover new elements.
---> we can know the group of element, its family and nature of chemical bond.
