What else can I help you with?
Are alkali and alkaline earth metals are not reactive?
No. The alkali and alkaline earth metals are very reactive.
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 Alkaline earth metals are harder than alkali metals?
It is because alkali metals are larger in size than alkaline earth metals.Also, the effective nuclear charge is more in case of alkaline earth metals. This makes their ionization enthalpies larger than alkali metals.
Is the alkali metal more reactive than an alkaline-earth metal?
Yes, alkali metals are more reactive than alkaline-earth metals. All atoms want to have 8 electrons in their outer shells. Alkali metals have to give one electron away, where as alkaline-earth metals need to give two away which is less energetically favorable.
What are characteristic property of the alkaline earth metals?
they are harder than alkali metals
Are ions of alkali metals larger or smaller than ions of alkaline metals from the same period?
larger
Are ions of alkali metals larger or smaller than ions or alkaline earth metals from the same period?
larger
Is the ionization energy of alkali metals larger or smaller than the alkaline earth metals in the same period?
It is about first ionization energy. It is less than alkaline earth metals.
How does the density of the alkaline earth metal compare with alkali metal?
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.
Are ions of alkali metals larger or smallest than ions of alkaline earth metals from the same period?
Ions of alkali metals are generally larger than ions of alkaline earth metals from the same period because alkali metals have only one outer electron, leading to a larger atomic radius and therefore a larger ion size compared to alkaline earth metals, which have two outer electrons.
How many Alkaline and Alkali Metals are there?
Six alkali metals and six alkaline earths.
Are alkali and alkaline earth metals are not reactive?
No. The alkali and alkaline earth metals are very reactive.
Which is more metallic alkaline metals or alkaline earth metals?
alkali metals
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.
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.
In what ways do alkali metals and alkaline earth metals differ?
Alkali metals and alkaline earth metals differ in their reactivity and properties. Alkali metals are more reactive and have one electron in their outer shell, while alkaline earth metals are less reactive and have two electrons in their outer shell. Additionally, alkali metals are softer and have lower melting points compared to alkaline earth metals.
What are the key differences between alkali metals and alkaline earth metals?
Alkali metals are in Group 1 of the periodic table and are highly reactive, while alkaline earth metals are in Group 2 and are less reactive. Alkali metals have one electron in their outer shell, while alkaline earth metals have two. Alkali metals are softer and have lower melting points compared to alkaline earth metals.
