Yes, all are alkali metals.
Alkali metals are the metals in family/group I.Lithium, sodium, potassium, Rubidium, Cesium, Francium are Alkali metals.
Lithium Sodium Potassium Rubidium Cesium Francium
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.
They are the metals in group 1 of the periodic table: lithium, sodium, potassium, rubidium, cesium, and francium.
They are the metals in group 1 of the Periodic Table: lithium, sodium, potassium, rubidium, cesium, and francium.
Group 1: Alkali Metals - Sodium - Potassium - Rubidium - Cesium - Francium
The Alkali Metals are: -lithium -sodium -potassium -rubidium -cesium -francium These metals are silvery solids with low densities and melting points.
Alkali metals include lithium, sodium, potassium, rubidium, cesium, and francium. These metals are located in group 1 of the periodic table and are highly reactive due to their tendency to lose a single electron to achieve stability.
The elements designated as alkali metals are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). They are all located in Group 1 of the periodic table. Alkali metals are highly reactive and tend to form ionic compounds with nonmetals.
Cesium is the most chemically reactive metal
Francium and cesium, the two with the highest atomic numbers.
Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Cesium (Cs), and Francium (Fr) are elements in the alkali metal family. They are highly reactive, soft metals that readily lose their outer electron to become positively charged ions.
