Because everthing is different. What is difficult is finding two things that are the same. However, the extreme dissimilarities of snowflakes is remarkable.

The really amazing thing is water. It is a very unusual molecule in many ways. One of these is that it can crystalize in more than 10 different forms (comonly we see ice and snow). Most substances have only one stable solid cristal forms.

In large part this is due to hydrogen bonding. Hydrogen bonds in water are so strong that as water solidifies it alters the crystalline structure, and exactly how this alteration occurs depends on the vagaries of the multiple weak intermolecular forces (van der Wall's, London forces ect.). As a result, the temperature, barometric pressure, humidity, incident photon flux, electrostatic ambience, impurities and several other factors which for most substances do not significantly alter the cristalline structure of the much stronger covalent and/or ionic bonds are strong enough to affect the much weaker hydrogen bond.

The hydrogen bond of water is not as strong as that of HF, where it reaches ranges near true covalance, yet strong enough to change cristalline structure.

The truly bizarre behavious of water is the subject of many books. I have tried to give a partil answer to a truly complex subject.


How does chirality arise?

Yes, I like pickles a lot, and relish and almost anthing else made with pickles BUT I do NOT like actual fresh unprocessed cucumbers at all.

Do you pickle anything with the left over juice in the pickle jar?
