Chemically francium is similar to caesium.
The period 6 element with chemical properties most like sodium is francium. Francium is also an alkali metal like sodium and exhibits similar reactivity due to having one valence electron in its outer shell. However, francium is highly radioactive and unstable, making it difficult to study its chemical properties in depth.
Francium has the largest atomic radius among all elements.
The chemical symbol Fr is derived of course from francium - the first two letters; it is a rule in the system of naming chemical elements.
Fluorine is the element with the highest electronegativity value.
The most metallic element after francium is cesium. Cesium is located in Group 1 of the periodic table and has properties that are characteristic of metals, such as high electrical conductivity and metallic luster.
The chemistry of francium is not known; francium has properties similar to caesium.
