It came from the alchemists in the Middle Ages because these elements were unchanged by fire.
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.
Barium is the largest alkaline earth metal due to its larger atomic size compared to the other alkaline earth metals like magnesium, calcium, strontium, and radium.
alkali earth metals are resistant to fire.
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.
Alkaline earth metals have 2 valence electrons.
