This element is caesium.
Francium is considered the most metallic element. It is an alkali metal with the highest metallic character due to its low ionization energy and ability to readily lose electrons. However, francium is extremely rare and highly radioactive.
Francium is a non metallic element. Mass number of it is 223.
Francium is more metallic than cesium. It is an alkali metal located below cesium in the periodic table and is the most reactive metal known.
Assuming that "least nonmetallic" means the same as "most metallic", francium.
Francium is the largest alkali metal, but it is not the largest or most reactive metal overall. It is highly reactive due to its position on the periodic table, which means it will react violently with water and air. However, there are other metals that are more reactive than francium, such as cesium and potassium.
Francium is the most metallic element. :)
The most metallic element on the planet is Francium. It is the last element to be discovered that was not made synthetically.
Francium is considered the most metallic element. It is an alkali metal with the highest metallic character due to its low ionization energy and ability to readily lose electrons. However, francium is extremely rare and highly radioactive.
It should be noted that francium is not the most reactive element, but is the most reactive metallic element. Francium has the lowest electronegativity and the greatest electropositivity; the chemistry of francium is practically unknown today.
francium, an alkali metal
Francium is a non metallic element. Mass number of it is 223.
most metals are metallic in a way. the periodic table consists of 3 different types of elements metals, non metals and metalloids the most metallic are the metals because they posses the most metal like properties.
Francium
Not known, probably a metallic appearance.
Francium is one such.
Francium followed by cesium
Conductor of electricity are compounds that allow electricity to pass through. They are metallic and sometimes ductile and malleable. Very common is iron. The most metallic element is francium.
