Francium doesn't exist in air.
Francium was found by Marguerite Derey of the Curie Institute of France in 1939.
Francium is a highly radioactive and unstable element that is never found in its pure form in nature. If it were to be touched, it would likely react explosively with water or air. Due to its extreme rarity and radioactivity, no one has ever touched or felt francium.
Francium is a member of the alkali metals family.
Natural francium exist in uranium and thorium ores.Artificial francium is obtained in particle accelerators.
Francium is not exclusively found in France, but rather, it is found throughout the Earth in extremely small quantities. Francium was discovered by a French scientist, Marguerite Perey.
Francium exist in uranium and thorium ores but it is not exploitable.
The most reactive metal is francium. Francium is a highly unstable alkali metal and is usually found in trace amounts in uranium and thorium ores. It readily reacts with air and water, making it one of the most reactive elements known.
francium is commonly found as hard rock unless it comes from gravestones
It was found in 1939.
Francium exist in infinitesimal concentrations in uranium and thorium ores.
It is estimated that only approx. 30 g francium exist on the Earth.
In the nature francium exists only in infinitesimal amounts and because of this, it is considered generally an artificial element. Francium reacts with water.
