Chapter 6, Problem 32A

Interpretation Introduction

Interpretation:

The items on the left needs to be matched with its corresponding group on the right.

Concept introduction:

There are 4 blocks in the periodic table: s-block, p-block, d-block and f-block. Here, s-block consists of groups I and II, p-block consists of group 13 to 18 and d-block consists of group 3 to 12.

Answer to Problem 32A

Correct match of items on the left with its corresponding group on the right is as follows:

a. Alkali metals	2. Group 1
b. Halogens	4. Group 17
c. Alkaline earth metals	3. Group 2
d. Noble gases	1. Group 18

Explanation of Solution

The s-block of the periodic table consists of two groups Group I and II. Group I is alkali metals and group II is alkaline earth metals. So, ‘a’ matches with ‘2’ and ‘c’ matches with ‘3’. The group 17 of the periodic table contains halogens, such as fluorine, chlorine, bromine etc and group 18 of the periodic table contains noble gases, such as, helium, neon, argon etc. So, ‘b’ matches with ‘4’ and ‘d’ matches with ‘1’.

Conclusion

Group 1 elements are alkali metals, group II elements are alkaline earth metals, group 17 elements are halogens and group 18 elements are noble gases.
