Question

why do noble gases have the largest atomic radii in their respective periods?​

Answer 1

Answer:

Inert gases usually do not form any covalent bond. Hence, in the crystals of Noble gases, there are no chemical forces between atoms. ... Since, the Van der Waals radii are larger than the covalent radii, the inert gases have largest atomic radii in the respective periods.

Answer 2

Answer:

let me try

Explanation:

Inert gases usually do not form any covalent bond. Hence, in the crystals of Noble gases, there are no chemical forces between atoms. ... Since, the Van der Waals radii are larger than the covalent radii, the inert gases have largest atomic radii in the respective periods.
