The atomic radii of the atoms in the group 1 increases down the group as we go from Hydrogen to Francium.
<h3>What is atomic radii ?</h3>
The total distance from the nucleus of an atom to the outermost orbital of its electron is known as its atomic radii or atomic radius.
As we go down the group, the number of orbits or shell increases.
Hence, atomic radii of the atoms in the group 1 increases down the group as we go from Hydrogen to Francium.
