MCQ
The correct order of density is
- A$Be > Mg > Ca > Sr$
- B$Sr > Ca > Mg > Be$
- ✓$Sr > Be > Mg > Ca$
- D$Be > Sr > Mg > Ca$
✓
Answer
Correct option: C.
$Sr > Be > Mg > Ca$
c
In $II'A'$ group density decreases down the group till $Ca$ and after that it increases.Correct order of density is $Sr > Be > Mg > Ca$
