1.	Given below are the atomic radii of some elements of second period. `{:("Element",B,O,N,C,),("Atomic Radius in pm",88,66,74,77,):}` Arrange these elements in the increasing order of their atomic number. Give reason for your answer.
Answer» Along a period, the atomic numbers of the elements increase and atomic radii decrease. This means that the two are inversely proportional to each other. Increasing order of atomic numbers : `BltCltNltO.`

Shailesh lies in a bigh industrial city having a large number of chemical industries onits outskirts. This city has also a very heavy traffic density. There is a big lake in the middle of this city which has much less water left init but the lake has still a large number of fish in it. During the last one and a half months, there ha been to much rain in the city with the pH of rain water being about 5.5. One day people found that many fish in the lake ha died. No one knew the reason for the death of fish in the lake or how the death of remaining fish in the lake could be prevented. Shailesh, who is a student of class X could understand the reason for the death of fish in lake. He also suggested an immediate solutioin for the prevention of death of more fish in the lake water. (a) What conclusion do you draw the fact that the rain water has a pH of about 5.5? What name is given to such a rain? (b) What makes the pH of rain water to be about 5.5? (c) What happens to lake water when too much rain water haivng pH of 5.5 collects in it? (d) Why have the fish died after the heavy rains? (e) Why suggestion do you think has been made by Shailesh to prevent the death of more fish in the lake? Why (f) What values are displayed by Shailesh in this episode?
