The atomic radius, which is the distance from the center of the nucleus of one atom to the center of the adjacent atom divided by two, of francium is 260 pm. This is measured when two francium atoms are covalently bonded, therefore having a covalent radius of 260 pm.
This covalent atomic radius is 2,6 ångströms.

Caesium atom has a larger atomic radius.
The atomic radius of silicon is approx. 0,11 nm.
Both atoms have the same van der Waal's radius (2.00) Radii that are not available in either of these publications have RvdW 2.00 A. However, Caesium has a greater covalent radius (1.67) as compared to that of Radon (1.50) See the link for more info.
The negative ionic radius is larger than the neutral atomic radius
because they both have different radius ratio so they have different structure. radius ratio=radius of cations/ radius of anions
The atomic radius of caesium is practically identical to the atomic radius of francium.
Caesium atom has a larger atomic radius.
The covalent atomic radius of francium is 260 pm.The covalent atomic radius of caesium is 244 pm.
The empirical atomic radius of rubidium is 235 pm.The empirical atomic radius of caesium is 260 pm.The empirical atomic radius of francium is supposed to be approx. 260 pm.
The atomic radius of francium and caesium are considered to be equal.
Caesium (260 pm) has a larger covalent atomic radius than beryllium (105 pm).
The atomic radius of silicon is approx. 0,11 nm.
First, the value of the atomic radius is not fixed, but depends on the definition you're using. Second, no element has an atomic radius as large as 152 nm. All atomic radii are about 1000 times smaller than that. Finally, assuming that you meant to say 152 pm, lithium has a metallic radus of 152 pm, oxygen has a van der Waals radius of 152 pm, and cobalt has a calculated atomic radius of 152 pm.
It is a difference between the empirical and the calculated atomic radius of an element; also all the values are only approximates. The empirical atomic radius of sulphur, phosphorous and chlorine is 100 pm. The calculated atomic radius of phosphorous is 98 pm.
The farther to the left and toward the bottom of the periodic table, the lower the electronegativity, and the larger the atomic radius. Calcium has a large atomic radius in comparison to elements in it's own period. What are you comparing calcium too? Calcium does have a large radius but not the largest, the largest is Cesium.

The empirical atomic radius of carbon is 70 pm.
