WebAnswer (1 of 4): The reactions with oxygen and chlorine could give some serious fireworks, more so for cesium than for lithium. With chlorine you’d probably just get LiCl, NaCl etc. … WebAs alkali metals have the highest electropositivity, they react with a wide range of nonmetals. Reactions involving oxygen Alkali metals tend to produce ionic solids with an oxidation number of +1. As a result, neutral substances containing oxygen can be easily categorised based on the oxygen species involved.
