The atomic radius of caesium is practically identical to the atomic radius of francium.
The atomic radius of francium and caesium are considered to be equal.
Rubidium
Atomic radii have not been measured or calculated based on theoretical principles for all of the elements. However, based on the information available in the wikipedia tables of atomic radii it would appear that the largest atom will prove to be that of francium.
The element cesium, at the left of row 6, is often cited as having the largest radius.However, francium in row 7 may be larger. There is almost no francium on Earth,as its half-life is 21.8 minutes.*The elements of the lower left hand side of the periodic table have the largest atomic radius. The upper right has the smallest.
