Alkaline Earth Metals . The alkaline earth metals are found in group IIA of the periodic table, which is the second column of elements. All of the alkaline earth metal atoms have a +2 oxidation state. Like the alkali metals, these elements are found in compounds rather than pure form. Alkaline earths are reactive but less so than alkali …

Abstract. The mechanics of large-strain deformation in cutting of metals is discussed, primarily from viewpoint of recent developments in in situ analysis of plastic flow and microstructure characterization. It is shown that a broad range of deformation parameters can be accessed in chip formation—strains of 1–10, strain rates of 10–105/s, …

Because of their tendency to form cations, alkali metals are highly reducing. All react vigorously with water to give hydroxides. 2 M(s) + 2 H2O(l) → 2 M + + 2 OH − + H2(g) (M = = Li, Na, K, Rb, Cs) The reactions are all exothermic and often lead to combustion of the evolved H 2 gas. As a result, while Li usually just fizzes as it reacts ...
