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 covalent atomic radius of francium is 260 pm.The covalent atomic radius of caesium is 244 pm.
Francium. The elements of the lower left hand side of the periodic table have the largest atomic radius. The upper right has the smallest.
It doesn't. Francium has the largest atomic radius because it has the most energy levels in period seven of the periodic table, and the least number of protons.
The radius of strontium is smaller than the radius of rubidium.
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.
Rubidium
Rubidium.
The atomic radius of caesium is practically identical to the atomic radius of francium.
The covalent atomic radius of francium is 260 pm.The covalent atomic radius of caesium is 244 pm.
The atomic radius of francium and caesium are considered to be equal.
Cesium (Cs) has an atomic radius of 265 picometers.
Rubidium Rubidium has atomic mass 85.5.
Francium has the largest atomic radius in Group 1 of the Periodic Table.
francium
The covalent atomic radius of francium is 260 pm and this value is not small.
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.
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.
