The alkaline earth metals are shiny, silvery-white, and somewhat reactive metals at standard temperature and pressure. All the alkaline earth metals readily lose their two outermost electrons to form cations with a 2+ charge. All of the alkaline earth metals except magnesium and strontium have at least one naturally occurring radioisotope.

The alkaline earth group as a whole stands in marked contrast to transi-tion metals and post-transitransi-tion metals. For example, most of the met-als in the periodic table form insoluble precipitates with the sulfide ion (S 2– ), with the result that sulfide ores of transition and post-transition metals are very common in Earth's crust.

Tremendous research efforts have thus been devoted to the design and development of hydrides of lightweight elements (HLEs). A prominent feature of these materials is the indispensable ingredient of alkali/alkaline earth cations. Alkali alkaline earth metals (AMs) are highly reactive and have a rich coordination chemistry.

Most of the elements in the periodic table are metals, which include alkali metals, alkaline earth metals, transition metals, lanthanides and actinides. The metals are present on the left side of the periodic table. They are separated from the nonmetals by a zigzag line that passes through metalloid elements such as boron, silicon, arsenic. Chat
