These metals are natually found deep in the earth's crust. They are one of the few metals on the Periodic Table that aren't man- made or are not the result of two elements joining together.
What else can I help you with?
Why are earth alkali metals called earth alkali metals?
Alkali earth metals are named after their oxides, alkaline earth.
Is alkali the only earth metal?
No, alkali metals are not the only earth metals. Earth metals include both alkali metals and alkaline earth metals. Alkaline earth metals are a group of elements in the periodic table that are chemically similar to, but less reactive than, alkali metals. Examples of alkaline earth metals include magnesium, calcium, and barium.
Why alkali metals are called earth metals?
Alkaline earth metals or the group II metals are called earth metals because they are mostly found as minerals in the earth's crust and constitute a major part of it.
Why the melting point boiling point and densities of alkaline earth metals are higher than alkali earth metals?
Alkaline earth metals do not exist , only alkali earth metals
Why were they named rare earth metals?
They were rare metals that are found in the earth.
What are the key differences between alkaline earth metals and alkali 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.
What are the classes of elements on the periodic table?
non-metals .... alkali metals....transition metals....alkali earth metals....rare earth metals....other metals....halogens....inert elements
How many alkailan earth metals?
There are 6 alkaline earth metals. They are metals Be,Mg,Ca,Sr and Ba.
Is alkaline earth metal in the group of metals nonmetals metalloids or diatomic molecule?
The alkaline earth metals are metals!
What are the chemical groups on the periodic table?
Alkali metals, Alkali Earth metals, Rare Earth metals, Transition metals, Non metals, Halogens, Inert gases
Elements in group 2 are called?
Group 2 elements in the periodic table are the alkaline earth metals.
What are metals that are less reactive than alkali metals and alkaline-earth metals?
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.
