Question

Why does noble gases have comparatively large atomic sizes

Answer 1

Please mark it as the brainliest answer.


It is so because in case of inert ornoble gases all the orbitals arecompletely filled means they have s2p6 configuration and hence inter electronic repulsions are maximum. Moreover in case of noble gases atomic radius is determined by vandervals radius which is larger than both ionic as well as covalent radii.

Answer 2

because the atomic size increases across the period and noble gases or 18 group Elements lie at the end of the periodic table
