The shape of a crystal reflects the arrangement of the particle within the solid how do allotropes of an element differ allotropes are different molecular forms of the same element in the same physical state. The first thing we notice about a crystal is the presence of planes — called faces — which constitute the external boundaries of the solid of course, any solid, including non-crystalline glass, can be carved, molded or machined to display planar faces examples of these can be found in any dollar store display of costume jewelry.
