D

8 and 54

Text Solution

Verified by Experts

The correct Answer is:
C
The magic number is 2,8,8,18,18,32 according to which the elements are arranged in the periodic table. As the atomic number of the element is `10`, so, it will resemble the elements with atomic number `=10-8=2`, `10+8=18`, `18+18=36`, `36+18=54`. This element resembles the element with atomic number `2,54`.
