Question

Noble gases have comparatively large atomic size, why?
​

Answer 1

Answer:

Now, the actual reason of that why noble gases have comparatively large atomic sizes is because in case of inert or noble gases all the orbitals are completely filled means they have s2p6 configuration and hence inter electronic repulsions are maximum resulting they do not form molecules, Moreover in case of noble ...

Answer 2

Explanation:

The noble gases have comparatively large atomic sizes as the atomic radii corresponds to Van der waals radii which are always large. Number of electrons increases as we move from left to right in a period. The last element in each period is the noble gas.
