Why did it take another 80 years to discover francium after all the other alkali metals?

Francium is a very unstable element it is estimated that only about 30 grams exist in the earth's crust. Scientists knew that an element like Francium should exist but had yet to find it. It was found in very small amount in uranium ore (only a few atoms) noticed by it's distinct radiation as the most stable isotope has a half-life of on 22 minutes.

What is francium and the alkali metals?
Francium is a member of the alkali metals group (group 1 of the periodic table).
All alkali metals except francium had been disconerd by 1860 why did it take scientists another 80 years to find francium?
Francium is the second rarest element on earth so that's probably why it took a little longer to discover.
What family is francium found in?
Francium is a member of the alkali metals family.
Francium alkali family?
Yes, francium is a member of the alkali metals family (group 1).
Are cesium potassium and francium all alkali metals?
Yes, all are alkali metals.
What block is francium in?
Francium is in the group 1 of the periodic table (alkali metals).
Are alkali metals in groupe 1 elements?
Alkali metals are the metals in family/group I.Lithium, sodium, potassium, Rubidium, Cesium, Francium are Alkali metals.
Where are the alkali metals?
The alkali metals are the metals found in group I, includinng lithium, sodium, potassium, rubidium, caesium and francium.
All of the alkali metals except francium were discovered by 1860. Why did it take scientists nearly another 80 years to discover francium?
Francium is named after France, which is where the element was isolated in 1939 by Marguerite Perey. Traces of francium occur naturally in uranium-containing minerals. francium is very rare so it took time to find it (i think)
What is the group number for francium?
Francium is in the group 1 (alkali metals) of the periodic table.
What period and group is francium in?
Francium is amrmber of the alkali metal familiy (group 1 in the Periodic Table of Mendeleev): Li, Na, K, Rb, Cs, Fr.
Francium reacting with water?
As other alkali metals francium can react with water; but unfortunately we don't have francium for this experiment !
