They are submerged in kerosene or other oil solutions to prevent them from reacting with the water vapor in the air and combusting.
Alkaline metals and alkaline earth metals form their oxides when burnt. These oxides are base.
alkali metals
The alkaline earth metals are metals!
Group 2 elements in the periodic table are the alkaline earth metals.
Six alkali metals and six alkaline earths.
Potassium, sodium, and lithium are softer and more reactive than other metals. They are typically stored in oil or kerosene to prevent them from reacting with moisture in the air.
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.
No. The alkali and alkaline earth metals are very reactive.
Radium is the radioactive metal among alkaline earth metals.
no
Yes When metals react with water they produce a metal hydroxide, this contains an OH- ion (which accepts protons and is therefore alkaline) This makes all metals alkaline.
Transition metals such as copper, silver, and gold are less reactive than alkali metals and alkaline-earth metals. These metals are less likely to react vigorously with water or air compared to alkali and alkaline-earth metals.
