Alkali Metals Alkaline Earth Metals. Alkaline earth metals are weak reducing agent than the corresponding alkali metals which have lower ionization enthalpies and comparatively bigger atomic sizes. Alkaline earth metals are metals that have two valence electrons in their outermost shell. The elements are beryllium Be magnesium Mg calcium Ca strontium Sr barium Ba and radium Ra. The alkaline earth metals are less reactive than the alkali metals.
Alkali and alkaline earth metals respectively. Alkaline earths have low electron affinities and low electronegativities. From lithium Li through francium Fr in Group IA and beryllium Be through radium Ra in Group IIA the rest of the alkali and alkaline earth metals share a number of physical characteristics such as. The alkaline earths possess many of the characteristic properties of metals. The elements are beryllium Be magnesium Mg calcium Ca strontium Sr barium Ba and radium Ra. Alkali metals are very reactive because they contain a single valence electron.
While not as reactive as the alkali metals this family knows how to make bonds very easily.
Alkali and alkaline earth metals respectively. Alkali metals are very reactive because they contain a single valence electron. 52 Alkaline earth metals The alkaline earth metals beryllium magnesium calcium strontium barium and radium are the second most reactive metals in the periodic table Table 37 and like the Group 1 metals have increasing reactivity in the higher periods. The members of the alkaline earth metals include. The alkaline earth metals are less reactive than the alkali metals. All alkaline earth elements have an oxidation number of 2 making them very reactive.
