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.

Is silicon a alkali metal or a alkaline earth metal?
Silicon is neither an alkali metal nor an alkaline earth metal. It is a metalloid that falls within the p-block of the periodic table.
Alkali metal hydroxides and alkaline earth metal hydroxides are?
Alkali metal hydroxides are strong bases that are highly water-soluble, forming alkaline solutions. Alkaline earth metal hydroxides are also bases but are less soluble in water compared to alkali metal hydroxides, resulting in less alkaline solutions.
3. Where are the most active metals (alkali &alkaline earth) located?
The most active metals, including alkali metals and alkaline earth metals, are located in groups 1 and 2 of the periodic table, respectively. Alkali metals are in group 1, while alkaline earth metals are in group 2. These metals are highly reactive due to their tendency to lose electrons and form positive ions.
What is the family name that calcium is in?
Group 2 (alkaline earth metals): lithium, sodium, potassium, caesium, rubidium, francium.
What is the family name for sodium?
Sodium is not a living thing. and hence, no family. but it belongs to the alkaline earth metals. Sodium is an Alkaline metal. The Alkaline Earths are the next column over.
Are alkali and alkaline earth metals are not reactive?
No. The alkali and alkaline earth metals are very reactive.
Is beryllium alkali metal or alkaline earth metal?
It is an alkaline earth element
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.
Is magnesium and alkali metal?
It is not a alkaline metal.It is a alkaline earth metal.
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
Which is more metallic alkaline metals or alkaline earth metals?
alkali metals
Are alkali metal and alkaline earht metals similar?
Alkali metals and alkaline earth metals are both groups of elements found in the periodic table. They have similar characteristics in that they are both highly reactive, low-density metals with low melting points. However, alkali metals are located in group 1 of the periodic table, while alkaline earth metals are located in group 2, and they have different chemical properties and reactivities.
Is alkali metal a calcium?
No, it is an alkaline-earth metal.
What is the difference between alkali metals and alkali earth metals?
Alkali metals are from Group 1 of the Periodic table and have a single electron in their outer shell. Alkaline-Earth metals are in group 2 of the periodic table and have 2 electrons in their outer shell.
How does the reactivity of an alkaline earth metal compare with that of alkali metal in the same period?
Alkaline earth metals are less reactive than alkali metals in the same period because they have higher ionization energies and are less likely to lose electrons. Alkali metals readily lose their outermost electron to form a +1 charge, whereas alkaline earth metals require more energy to lose their outermost two electrons to form a +2 charge.
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.
