Match the atomic numbers given in Column- I with the block in which the element is placed in Column - II and mark the appropriate choice.

	Column-I  (Atomic number)		Column II (Block)
A	62	I	d-block
B	47	II	p-block
C	56	III	f-block
D	53	IV	s-block

	A	B	C	D
1)	III	I	IV	II
2)	I	II	III	IV
3)	II	IV	I	III
4)	IV	I	II	III

Z= 62....f-block
   Z=58 to 71 are lanthanoids.
B) Z=47....d-block
   47- 18=29.We know Z=29 is copper
   So Z=47 belongs to copper group.
C) Z=56....s-block
   56-18=38
   38-18=20
   So Z=56 belongs to "Ca" group.
D) Z=53....p-block
   53-18=35
   35-18=17
   So Z=53 belongs to "Cl" group.
