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.
they are harder than alkali metals
No. The alkali and alkaline earth metals are very reactive.
Alkaline earth metals do not exist , only alkali earth metals
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.
The alkali (Group 1) and alkaline earth (Group 2) metals occupy the s-block because their outermost electrons are in the s sublevel.
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.

The group you're referring to is the group of alkaline earth metals. They are shiny solids that are harder than alkali metals. Examples include calcium, magnesium, and barium.
No. The alkali and alkaline earth metals are very reactive.
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.
Alkali earth metals are named after their oxides, alkaline earth.

Alkali metals and alkaline earth metals are both groups of elements on the periodic table, but they have distinct differences in their properties and reactivity. Alkali metals are located in Group 1 of the periodic table and are highly reactive, soft metals that easily lose their outermost electron to form positive ions. In contrast, alkaline earth metals are located in Group 2 and are less reactive than alkali metals, but still have a tendency to lose electrons to form positive ions. Alkaline earth metals are harder and have higher melting points compared to alkali metals. Overall, alkali metals are more reactive and have lower melting points than alkaline earth metals.
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.
