Hint: Hexagonal columns, hexagonal plates, dendritic crystals, and diamond dust are examples of ice crystals that show atomic ordering on different length scales. Ice crystals form cirrus clouds in the free air and the hydrometeor known as "ice crystals" near the ground.

Water molecules, which are made up of two hydrogen atoms and one oxygen atom, make up ice crystals. From the atomic nucleus, the two hydrogen atoms form a $104.5$- degree angle. Since the oxygen atom absorbs more electrons, the water molecule is slightly negative on one side and slightly positive on the other. As bipolar molecules in water freeze, they attract each other and form a hexagonal crystal lattice.
