Liquid the distances between the molecules become smaller. When the liquid reaches its freezing point the molecules will usually lock into a very specific order, called crystallizing, and the bonds between them become more rigid, changing the liquid into its solid state (unless supercooling occurs). Only two elements are liquid at standard conditions for temperature and pressure: mercury and bromine. Four more elements have melting points slightly above room temperature: francium, caesium, gallium and rubidium. Metal alloys that are liquid at room temperature include NaK, a sodium-potassium metal alloy, galinstan, a fusible alloy liquid, and some amalgams (alloys involving mercury). Pure
Liquid metal solution slowly, producing gallates like [Ga(OH)], which makes the surface of gallium negatively charged and cations accumulated nearby, and thus the electrically charged interface forms into a uniform diffuse electrical double layer (EDL) . The electrons flowing internally from Al to the liquid metal preferentially deoxidate the oxidized gallium near the Al, which alters the distribution of the charges across the EDL, leading to the generation of a potential gradient along the liquid metal surface. According to Lippmann's equation, the alteration of the EDL induces an imbalance of the surface tension on the liquid metal. Following the Young-Laplace equation, the
