WebThe ions are held by electrostatic charges in an ionic bond. /**/ Properties of ionic solids High melting points and boiling points due to strong ionic bonds. Most are solids at room temp. They are brittle - will shatter with a hammer. Usually soluble in water. Insoluble in non-polar solvents. Do not conduct electricity in solid state. WebQuasicrystals are exceptionally brittle. They have few dislocations, and those present have low mobility. Since metals bend by creating and moving dislocations, the near absence of dislocation motion causes brittleness. On the positive side, the difficulty of moving dislocations makes quasicrystals extremely hard. They strongly resist deformation. how is bubonic plague transmitted
