Question

in period the element with largest atomic volume belongs to which of the group​

Answer 1

Answer:

In the periodic table from left to right in a period the atomic volume first decreases then increases.

With increase in the atomic number, the nuclear charge increases but the number of shells in the atoms of all the elements in a given period remains the same. The attraction between the nucleus and the valence electrons increases. This decreases the atomic radius.

Thus, in a given period, the alkali metals have largest atomic volume, on moving from left to right in a period, the atomic volume decreases and halogens have smallest atomic volume  in a given period. The atomic volume of noble gases is comparatively larger as they have large van der Waals radii due to completed valence shell, with all electrons paired which causes greater repulsion.
