This might be attributed to its higher electropositivity, potentially also to thermodynamic instability of its bulk nitride, which, in the case of lithium with its very stable nitride, might serve as a sink. Lithium should be stored under argon. lithium to a dull redness in a stream of nitrogen, was the first to report the preparation of lithium nitride. As such, it can deprotonate hydrogen gas to form LiNH 2 and LiH, making it a useful for hydrogen storage (Ichikawa et al, 2004). Nitrogen trifluoride melts at –206 °C. Lithium was chosen for its well-understood electrochemistry and ability to activate nitrogen at ambient conditions. Lithium should be stored under argon. 1. At this potential, the lithium nitride rapidly and spontaneously breaks down to ammonia and lithium ions, completing the cycle. b)When the above reaction takes place, how many molecules of NH3 are produced?
