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 can move in free space and in various structural channels; surprisingly, it can also make its own deformation adjustment according to the width of the path along the path. The dynamic mechanism comes from two aspects. According to Rebinder's effect , liquid metal alloy EGaIn or Galinstan would penetrate into aluminum, destroying the oxide skin on Al surface and leading to the activation of Al. In NaOH solution, Al is the cathode and liquid metal works as the anode. the dissolution of Al on the cathode renders Al to lose electrons, Under the equilibrium state, gallium reacts with the alkali
