Francium would be expected to be soft, based on its being the highest Atomic Mass alkali metal. (It probably has never been made in large enough quantity for a hardness test!)
What else can I help you with?
Is francium harder than sodium?
Francium is softer than sodium. Francium is a highly reactive metal that is classified as the most electronegative element on the periodic table. Sodium is also a soft metal, but it is harder than francium.
Is francium a ductile?
Francium is not considered ductile because it is a highly reactive metal that is soft and easily deformed. Due to its extreme reactivity with air and moisture, it is difficult to handle and study in its pure form.
How easy is it to cut francium?
Francium is extremely unstable. The most stable isotope of francium has a half-life of only about 22 minutes. Other isotopes of francium have half-lives measured in microseconds. Scientists predict there is less than one ounce of francium in Earth's crust at any one time. Because of this instablilty, it would be much easier to go get a cup of coffee and wait for francium to cut itself apart.
Is francium strong?
Francium is a soft, highly reactive metal. It is the most unstable of all the naturally occurring elements due to its large atomic size and low electronegativity. It readily reacts with other elements, so it is typically stored in inert gas to prevent this.
How was francium named francium?
Francium was named after France, the country it was dicovered in.
Is francium a soft metal?
Very probable francium is a soft metal.
Is francium hard?
The hardness of francium cannot be measured.
What are the properties of francium?
francium is commonly found as hard rock unless it comes from gravestones
Is francium harder than sodium?
Francium is softer than sodium. Francium is a highly reactive metal that is classified as the most electronegative element on the periodic table. Sodium is also a soft metal, but it is harder than francium.
What shape is Francium?
As Francium is an Alkaline metal it has a lone electron in an outermost S orbital. Therefore the atom is perfectly spherical.
Is francium a ductile?
Francium is not considered ductile because it is a highly reactive metal that is soft and easily deformed. Due to its extreme reactivity with air and moisture, it is difficult to handle and study in its pure form.
Why was francium hard to discover?
because it only has a half life of 22 minutes so by the time any one could get to it the francium had died
Is brown soft or hard?
Hard
Why is francium so hard to detect?
The two natural isotopes of francium - 223Fr and 221Fr - are extremely rare (only ca. 30 g in the earth crust).
What is francium chloride?
Francium chloride is a radioactive chemical compound with the formula FrCl. It is predicted to be a white solid and is soluble in water. Its properties resemble caesium chloride. It is produced by the reaction of hydrochloric acid with francium metal. Source: Wikipedia
