Alkali metals can react explosively with water and it is textbook knowledge that this vigorous behaviour results from heat release, steam formation and ignition of the hydrogen gas that is produced. Here we suggest that the initial process enabling the a
Alkali metals are very reactive, and thus none occurs in a free state in the environment. They spontaneously react with oxygen, water, halogens , phosphorus, sulfur, and other substances; lithium even reacts with nitrogen. Reactions with water can be violent, with the evolution of hydrogen ...

Interaction of all 5 alkali metals with water under various circumstances has been discussed comparatively [2]. In a monograph covering properties, preparation, handling and applications of the enhanced reactivity of metals dispersed finely in hydrocarbon diluents, the hazardous nature of potassium ...
Analogous reactions with sodium form the divalent nickelate Na2NiO2. Coadsorption of the alkali metal and oxygen on clean Ni(110) provides for optimum nickelate formation, whereas the presence of water inhibits the formation of Ni3+ significantly. Similar experiments on NiO(100) suggest that the...

It's like the question I asked about a week ago, where my textbook gave both of the following reactions: 3NO2+ H2O 2HNO3+ NO and 2NO2+ H2O HNO3+ HNO2 and so which do I write for the test if they say "Nitrogen dioxide is bubbled into water?" (Which I still have no answer ...

Any of a group of soft metals that form alkali solutions when they combine with water. They include lithium, sodium, potassium, rubidium, cesium, and francium. Except for cesium, which has a gold sheen, alkali metals are white. The alkali metals have one electron in their outer shell, and...
