Why are they referred to as alkaline earth metals?
The name originates from the fact that the oxides of these steels produced an easy solutions when dissolved in water, and also they stayed solids at the temperatures available to the ancient alchemists. Prefer the team 1A elements, the alkaline earth metals space too reactive to be found in nature in your elemental form.
Which metal is strongest reducing agent?
The finest reducing metal is lithium, with the maximum an adverse value that electrode potential.
Are alkali metals soft or hard?
The alkali steels are solids at room temperature (except because that hydrogen), but have relatively low melt points: lithium melts at 181ºC, sodium at 98ºC, potassium in ~ 63ºC, rubidium at 39ºC, and cesium in ~ 28ºC. They are also relatively soft metals: sodium and potassium can be reduced with a butter knife.

Do alkali steels react with water?
Alkali metals react v water to produce heat, hydrogen gas, and also the equivalent metal hydroxide. The heat produced by this reaction may ignite the hydrogen or the metal itself, causing a fire or one explosion. The heavier alkali steels will react an ext violently through water.
