Today the only official name is francium.
As a metal, probably francium has a metallic appearance. We haven't a sufficient quantity of francium for observations, measurements and other studies.
Francium was named after France, the country it was dicovered in.
No francium is not magnetic (i.e ferromagnetic like a fridge magnet!) it is like the other group 1 metals paramagnetic, it is (slightly) attracted by a magnetic field, but there is no possibilty of permanant magnetism.
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 supposed to be very reactive but the chemistry of francium is not known.
Yes, Francium has a couple older names. The first time it was discovered, it was called "eka-caesium." The second name was "moldavium."
Francium can be solid, liquid or gaseous.
The chemistry of francium is not known but it is supposed that francium can react with the majority of nonmetals.
As other alkali metals francium can react with water; but unfortunately we don't have francium for this experiment !
The chemistry of francium is not known but francium is considered the most reactive metal.
The existence of francium in cosmos was not proved.
As a metal, probably francium has a metallic appearance. We haven't a sufficient quantity of francium for observations, measurements and other studies.
The chemistry of francium is not experimentally known; it is only estimated. Francium should be have properties similar to caesium.
The chemical reactions of francium are probably similar to the reactions of caesium or rubidium.
Alkali metals are: lithium, sodium, potassium, rubidium, caesium and francium.
No...Caesium and Francium are both Alkali metals. They cannot bond ionically with each other.
