Introduction The alkali and alkaline earth metals comprise the first two columns of the periodic table, traditionally referred to as Groups IA and IIA, respectively (Figure 1 ). Although H is technically considered a member of Group IA, it is not an alkali metal like the rest of the ...
A single metal-metal bonding exists between the two metal atoms. For the same alkaline earth metal, the metal–metal bond in M2(η -As5)2 is weaker than that in M2(η -P5). Nucleus independent chemical shift (NICS) values confirm that the planar exhibits characteristics of aromaticity in...
e.g., a metal-cored consumable welding wire, configured to serve as an electrode, where the welding wire comprises one or more alkaline earth metal elements at a concentration between 0.005% and 10% on the basis of a total weight of the welding wire, and where the atoms of the one...
