Web7 apr. 2024 · As a typical demonstration of chemically responsive liquid metal smart materials, researchers induced motion in liquid metal droplets based on the difference in an acid–base concentration (Figure 4c). The mechanism underlying this phenomenon involved a change in the EDL of the liquid metal droplets. WebAnswer: Alkali metals are highly reactive because their outermost electron shell leaves the outermost electron with a high energy relative to the adjacent, highly stable noble gas (i.e. sodium has one more electron than neon, potassium has one more electron than argon, etc.). The noble gases are ...
