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.

What are characteristic property of the alkaline earth metals?
they are harder than alkali metals
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
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 characteristics are shared by all alkali metals and alkaline earth metals?
They are highly- reactive metals
What are characteristic property of the alkaline earth metals?
they are harder than alkali metals
What are characteristic properties of alkaline earth metals?
they are harder than alkali metals
Why are alkaline earth metals harder than alkali metals?
i thought increase in size.
Are alkali and alkaline earth metals are not reactive?
No. The alkali and alkaline earth metals are very reactive.
Which element group is made up of shiny solids that are harder than alkali metals?
the alkaline earth metals
Why are earth alkali metals called earth alkali metals?
Alkali earth metals are named after their oxides, alkaline earth.
Do alkali metals react slower or faster than alkaline earth metals?
Alkali metals are more reactive than alkaline earth metals.
Which is more metallic alkaline metals or alkaline earth metals?
alkali metals
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
What is group 2A elements known as?
Alkaline Earth Metals
How do the alkali metals differ from the alkaline earth metals?
alkali metals have one valence electron, whereas alkaline earth metals have two valence electrons.
How are alkali metals different from alkaline metals?
The alkali metals are generally more reactive than the alkaline earth metals. They form 1+ ions while the alkaline earth metals form 2+ ions. Alkali metal compounds tend to be more soluble in water than alkaline earth metals.
