Radium
Most alkaline earth metals are in a solid state at room temperature.
Group 2 (alkaline earth metals): lithium, sodium, potassium, caesium, rubidium, francium.
Beryllium belongs to the alkaline earth metals family on the periodic table.
The density of alkaline earth metals is generally higher than that of alkali metals. This is because alkali metals have only one valence electron and are larger in size compared to alkaline earth metals, which have two valence electrons and are smaller in size. The higher density of alkaline earth metals is due to their more compact atomic structure.
Alkaline earth metals were named "earth" to differentiate them from alkali metals, which were known to form alkaline solutions when reacting with water. The term "alkaline" was added to indicate they were compounds with a high pH.
Barium has the largest electron affinity among the alkaline earth metals.
Alkaline metals and alkaline earth metals form their oxides when burnt. These oxides are base.
Group 2 elements in the periodic table are the alkaline earth metals.

The alkaline earth metals are metals!
No. The alkali and alkaline earth metals are very reactive.
Radium is the radioactive metal among alkaline earth metals.
Alkaline earth metals have two valence electrons, while alkali metals have one valence electron. Alkaline earth metals are harder and have higher melting points compared to alkali metals. Additionally, alkaline earth metals are less reactive than alkali metals.
Radium is in the alkaline earth metals.
