Can francium be created?
Francium can be produced by bombarding thorium with protons or by bombarding radium with neutrons. Francium’s most stable isotope, francium-223, has a half-life of about 22 minutes. It decays into radium-223 through beta decay or into astatine-219 through alpha decay.
Where can you find francium in everyday life?
Francium has been used in the field of research, chemistry and also in the atomic structure. It is used for diagnostics for curing cancers. It is also used in many spectroscopic experiments. Francium is a highly radioactive metal, and since it exhibits a short half-life, it does not have more impact on the environment.
Does francium occur naturally?
Francium is a naturally occurring radioactive decay product that pops up in thorium and uranium ores before it decays into either astatine, radium, or radon.
Where is francium found naturally?
Natural francium is the result of an alpha disintegration of actinium. It occurs naturally in uranium minerals, but the Earth’s crust probably contains less than 1 ounce of francium at any time. Francium can be made artificially if thorium is bombarded with protons.
How common is francium?
Francium occurs naturally to a very limited extent in uranium minerals. Nevertheless it has been estimated that there might be from 340 to 550 grams of francium in the earth’s crust at any one time. Francium is the second rarest element in the crust, after astatine.
What element family is francium?
alkali metal group
francium (Fr), heaviest chemical element of Group 1 (Ia) in the periodic table, the alkali metal group.
Has anyone found francium?
Francium was discovered by Marguerite Perey in France (from which the element takes its name) in 1939. It was the last element first discovered in nature, rather than by synthesis.
What is an interesting fact about francium?
Francium is the second rarest element in the Earth’s crust, next to astatine. Less than thirty grams of francium exists on Earth at any given time. Francium is the least electronegative of all the elements, therefore it should be the most chemically reactive alkali metal.
Who found francium?

Francium/Discoverers
The eventual discovery of element 87 was made in 1939 by a remarkable Frenchwoman, Marguerite Perey, who began life as a laboratory assistant to none other than Marie Curie in Paris.
Where is francium found in nature?
uranium minerals
Natural francium is the result of an alpha disintegration of actinium. It occurs naturally in uranium minerals, but the Earth’s crust probably contains less than 1 ounce of francium at any time. Francium can be made artificially if thorium is bombarded with protons.
