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!)
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.
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.
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.
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.
Francium was named after France, the country it was dicovered in.
Very probable francium is a soft metal.
The hardness of francium cannot be measured.
francium is commonly found as hard rock unless it comes from gravestones
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.
As Francium is an Alkaline metal it has a lone electron in an outermost S orbital. Therefore the atom is perfectly spherical.
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.
Hard
because it only has a half life of 22 minutes so by the time any one could get to it the francium had died
it is hard and sometimes soft
hard
soft you can bend and hard you can not
The two natural isotopes of francium - 223Fr and 221Fr - are extremely rare (only ca. 30 g in the earth crust).
