Fill in the blanks with the appropriate words in each case Element 'Z' in a sub-group 2[II A] is below element 'Y' in the same sub- group.The element 'Z' will be expected to have atomic size and metallic character than \( y \)
- A. lower, more
- B. lower, less
- C. higher, more
- D. higher, less
Step-by-step solution
In Group 2 (alkaline earth metals), as we move down the group, atomic size increases due to addition of new shells, and metallic character increases because the tendency to lose electrons becomes easier. Since Z is below Y, Z has larger atomic size and more metallic character.
