Transcript of Francium, The Periodic Table Element

Francium Discovered by Margaret
Perry, in Parris, France, during 1939. Exteremley unstable, it's longers half life being 22 seconds, its shortest being 12 microseconds. Type: Metal
Symbol: Fr
Atomic Number: 27
Atomic Mass: 273
Period: 1
Group Number: 7
Family: Alkali Metals If you drop Francium into a tub of water,
it'll blow a hole through the tub and
explode, even with just a small amount.
Also any Alkali metal will react explosively
with water.Lithium, Sodium, Magnesium,
Rubidium, Caesium, and Francium being
the most reactive, causing a bigger explosion.
As Francium is extremeley rare,
you will never hold it in your life. Scientists estimated that
only 20 to 30 grams can be found
on the earth's crust at one time. It's so rare that it has no price, it will not be sold to any one. Also, it is so rare that not many photos have been made of it. Francium can be found
only in the earth's core,
and uranium holds small
Traces of it.

Due to its instability and rarity, there are no commercial applications for francium. It has been used for research purposes in the fields of biology and of atomic structure. Its use as a potential diagnostic aid for various cancers has also been explored, but this application has been deemed impractical.
