Question

difference between alkali metals and alkaline earth metals

Answer 1

Simple alkali metals have +1 oxidation stated and alkali earth metals have +2 oxidatiom state but alkali earth metals are mostly abundant in earth than alkali metals...Both of them are good reducing agents....

Answer 2

We know that alkali metals are group I A elements having valency 1 and and alkalines earth metals are group II A elements with valency 2.Just like their names, they do not differ completely. As their names suggest, both form basic (alkaline) solutions.Because group I A elements have valency 1, they can easily give up 1 electron to achieve stability and are thus highly reactive (more reactive than alkaline earth metals). They all react with water to form strongly alkaline hydroxides. Hence group I elements are called Alkali metals.'Earth' is an old term applied by early chemists to nonmetallic substances that are insoluble in water and resistant to heating. Oxides of group II A elements show these properties of 'earth' metals. Group II elements also form basic (alkaline) hydroxides. Hence, group II elements are called Alkaline Earth metals.The elements of group II A (alkaline earth) have much higher melting points and boiling points compared to those of group I A (alkali metals). Thealkali also have a softer and more lighweight figure whereas the alkaline earth metals are much harderand denser. hope it help u
