The three elements X, Y and Z in a group have ionic radii $1.33 Α, 0.95 A a n d 0.60 A$ , respectively. Arrange them in increasing order of atomic numbers.

Open in App

Solution

While moving down the group, we know that size of an atom increases due to the addition of a shell to the element. Hence when the number of shells increases, naturally the atomic number will also increase.
Final answer:- Arrangement in increasing order of their atomic numbers- $Z < Y < X$ .
