why group 1 is known as alkaline earth metal
Answers
Answer:
becoz they are alkaline in nature and they are available on the earth's crust that's why they are alkaline earth metals
Answer:
Group 1 elements are called alkali metals because their oxides are soluble in water and group 2 elements are called alkaline earth metals as their oxides form in the earth and are water soluble.
Explanation:
The alkaline earth metals are named after the alkaline earths whose old-fashioned names were beryllia, magnesia, lime, strontia, and baryta, after their oxides. When mixed with water, these oxides are simple (alkaline).
Beryllium, magnesium, calcium, strontium, barium and radium are the elements in Group 2. For two reasons, these elements are referred to as Alkaline Earth metals, Their oxides remain in the crust of the earth and are very heat-stable.
In group 1 of the periodic table, alkali metals are the elements. The elements of Group 2 of the periodic table are alkaline earth metals. The key distinction between alkaline and alkali is that there is one valence electron in alkali metals, while two valence electrons are in alkaline earth metals.
