Question

Set of continuous atomic numbers of the elements present in the same group as well as same period
1)3, 11, 19
2)60, 61, 62
3)30, 31, 32
4) 88, 89, 90​

Answer 1

Answer:

2) 60,61,62

4) 88,89,99

both options 2 and 4 are correct

Answer 2

For the Set of continuous atomic numbers

Explanation:

We can find it by the Lantanide and actinide series

Lanthanide series= 58-71 and it belongs to

=6th period

=3rd group

Actinide series= 90-103 and it belongs to

=7th period

=3rd group

so the set of continuous atomic numbers of the elements in the same group as well as same period is 60,61,62 which exists between the Lanthanide series and 88,89,90 which before the Actinide series

so the answer is 2) 60,61,62 and 4) 88,89,90
