Winter is coming, and it’s always nice to explain how snowflakes form. =)
A snowflake is created when water vapor slowly freezes around a dust particle. The morphology of the snowflake depends on factors as :humidity and temperature that is created.
But, Why do snowflakes look the way they do?
Well, the chemical properties of atoms, dictate how they are arranged in a solid.
Water molecules have a V-shaped geometry, with an Oxygen atom at the vertex bonded with two Hydrogen atoms, protruding like a rabbit-ear antenna. The shape of the water molecule determines the geometry of its packing, which turns out to be an hexagon.
