alkali metals
Beryllium is the first element in the alkaline earth metals.
Beryllium, magnesium and barium are three more alkaline earth metals.
The alkali metals are more reactive.
Not it's not. Sodium is an Alkaline Metal, and Magnesium is an Alkaline Earth Metal, therefore Sodium is more reactant than Magnesium. It is because Alkaline Metals are more reactant 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.
Yes
Alkaline earth metals have a moderate reactivity level compared to other metals. They are less reactive than alkali metals, but more reactive than transition metals. Alkaline earth metals readily form ionic compounds with nonmetals due to their tendency to lose two electrons.
Alkaline earth metals have two outer electons. Alkali metals have one. It is more energetically favorable (easier) t oremove one electron than two making alkali metals more reactive than alkaline earths.
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.
The alkaline earth metals are in group 2 of the periodic table this means they have 2 electrons in each of their outermost energy 'shells'. The alkaline metals are in group 1 and only have 1 electron to lose in a reaction rather than 2. This means the alkaline metals react more readily.
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 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.
