In group 1 of the periodic table three elements X, Y and Z have atomic radii 133 pm, 95 pm and 65 pm respectively. Giving a reason, arrange them in the order of increasing atomic number in the group.

Explanation

To arrange the elements X, Y, and Z in order of increasing atomic number based on their atomic radii, we can follow these steps:

### Step 1: Identify the given atomic radii
The atomic radii of the elements are as follows:
- Element X: 133 pm
- Element Y: 95 pm
- Element Z: 65 pm
