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.
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)
Why did it take scientists nearly another 80 years to dicover Francium?
cause i needed a big pis and then got tired it was my fault it took so long [[[[:)
Was the discovery of Francium delayed because of a lack of technology at the time among other reasons?
Francium was found 80 years after the others because it is very rare on the Earths surface and there is less than an ounce of it in the earths crust. Also the fact that the technology was limited didn't help.
