Question

How can we measure the radius for noble gases?

Answer 1

Noble gases:

1. These are group 18 elements.
2. Noble gases are in a stable condition because they have entirely filled their outermost shells.
3. They are known as noble gases because of their stability, which prevents them from reacting with other elements.
4. Examples: Argon, neon, and krypton.

Measurement of radius:

1. The noble gases have an entirely filled outer shell, as we well know.
2. The inter-electronic repulsion is quite strong because of this packed electronic structure.
3. The electrons have a tendency to migrate apart from one another as a result of this repulsion.
4. This resulted in the atoms' sizes expanding.
5. Van der Waal's force, which is weak, holds the atoms of the noble gases together.
6. Therefore, the Van der Waals radius is used to calculate the atomic radius for noble gases.
7. This radius dwarfs all ionic and covalent radii in size.
