paring other group 1 metals .当 Li 放进水时 只有嘶嘶声(hissing sound)并无火出 但是相反Na进水时 个反应激好多 有声 又有火出. For barium nearly on the bottom position of group 2 with nearly largest atomic radius and thus have +56 nuclear charge . The distance beeen nucleus the...
更新1: One last question... If the first element of group 1 pares to the last element of group 2... Which is more reactive? And which element of group 2 equals to the reactivity of any element in group 1? For example Ba = Na?? Just for an example..Your question is...
This series are wool reactive dyestuffs with high performance. It contains double reactive groups, with its water fastness , high stability, good performance in wet fastness and free of heavy metals, can meet OeKo-Tex100 environmental demands. ...
If you don't have the chart of the activity series handy, you can also use trends in the periodic table to predict the reactivity of a metal or nonmetal. The most reactive metals belong to thealkali metalselement group. Reactivity increases as you move down the alkali metals group. The in...
MetalsReactivityActivationSynthetic methodsToday, the synthetic chemist has a large repertoire of metal activation methods at his disposal. After a first breakthrough was made at the beginning of the seventies with the introduction of the Rieke metals, a series of further, in part more efficient ...
of tantalum. The casting molds can be made of a homogeneous metal, but it is also possible to insert shells of the metals in question into a base body to form the boundaries of the mold cavities, whereas the base body itself consists of some other metal or alloy or of a nonmetal such...
