Worksheet on Structure of solids
Crystalline and amorphous solid are categories of solids.
Crystalline solids are bonded together in a regular pattern. A good example of Crystalline solid is quartz crystals SiO2.
Amorphous solids are made up of molecules or atoms and they don’t have regular arrangement. A good example of Amorphous solid is Glass.
