Francium - 1939
Francium is a member of the alkali metals group (group 1 of the periodic table).
Yes, francium is a member of the alkali metals family (group 1).
Francium is a member of the alkali metals family.
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)
Francium is in the period 7 and group 1 of the periodic table (alkali metals).
Yes, all are alkali metals.
Francium is in the group 1 of the periodic table (alkali metals).
Alkali metals are the metals in family/group I.Lithium, sodium, potassium, Rubidium, Cesium, Francium are Alkali metals.
The alkali metals are the metals found in group I, includinng lithium, sodium, potassium, rubidium, caesium and francium.
Francium is in the group 1 (alkali metals) of the periodic table.
2Fr + 2H2O -----> 2FrOH + H2 However, francium decays too quickly to exist in nature. A brilliant video for the alkali metals (except francium), can be found in related links
6: lithium(Li) ,sodium(Na) , potassium(K) , rubidium (Rb) , cesium (Cs) and Francium(Fr). Practically,only the first five can be termed alkali metals,because there is not enough Francium in the planet to examine its characteristics. Of course, the electron structure of the atom of Francium "proposes" an alkali metal.
