What family does francium belong to?
alkali metal group
francium (Fr), heaviest chemical element of Group 1 (Ia) in the periodic table, the alkali metal group.
Is francium naturally found?
Although considered a natural element, scientists estimate that there is no more than one ounce of francium in the earth’s crust at one time. Since there is so little naturally occurring francium on earth, scientists must produce francium in order to study it.
What element was named after Dmitri?
Mendelevium 101
Mendelevium 101. The first element to be identified one atom at a time was named after the main architect of the modern periodic table.
What is the origin name of element mercury?
The name mercury originated in 6th-century alchemy, in which the symbol of the planet was used to represent the metal; the chemical symbol Hg derives from the Latin hydrargyrum, “liquid silver.” Although its toxicity was recognized at an early date, its main application was for medical purposes.
What is the 92 element?
Uranium
Uranium is a silver-gray metallic chemical element in the actinide series of the periodic table that has the symbol U and atomic number 92. Uranium has the highest atomic weight of the naturally occurring elements.
How much francium is in the world?
As it turns out, francium was one of the last natural elements to be discovered, and is the second rarest after astatine. Estimates of the abundance of francium suggest that there is only about 30 g in the whole of the Earth’s crust.
What is the rarest element on earth?
astatine
A team of researchers using the ISOLDE nuclear-physics facility at CERN has measured for the first time the so-called electron affinity of the chemical element astatine, the rarest naturally occurring element on Earth.

How was francium named francium?
Francium, (the element that took its name from the country, France) was discovered by Marguerite Perey in France in 1939. She had discovered an element, while analyzing actinium’s decay sequence and named francium, in honour of her country.
