The covalent alkaline earth metal halide (X=Cl,Br,I) is:
MgX2
CaX2
BeX2
SrX2
Covalent alkaline earth metal halide:-
In chemical terms, all of the alkaline earth metals react with the Halogens to form the alkaline earth metal halides, all of which are ionic crystalline compounds except for Beryllium halide, which is covalent [esp. BeCl2].
A chain type of structure can be observed in the solid form of beryllium chloride.
These beryllium halides can be generally dissolved in organic solvents.
