The. CrystalsIce crystal Ice crystal Water ice in symmetrical shapes Ice crystals are solid water (known as ice) in symmetrical shapes including hexagonal columns, hexagonal plates, and dendritic crystals.[1] Ice crystals are responsible for various atmospheric optical displays and cloud formations.[1][2] This article needs additional citations for verification. (March 2022) A close-up of growing ice crystals displaying typical hexagonal symmetry Formation An example of a hexagonal plate (top) and a hexagonal column (bottom), typical ice crystal shapes At ambient temperature and pressure, water molecules have a V shape. The two hydrogen atoms bond to the oxygen atom at a 105° angle.[3] Ice crystals have a hexagonal crystal lattice, meaning the water molecules arrange themselves into layered hexagons upon freezing.[1] Slower crystal… (Source: Wikipedia)
