correct the mistakes in this statement

A vacancy is a point defect that occurs when an atom is missing from a lattice position. A perfect metal crystal would exhibit ductile behavior. Amorphous crystals have long range order which can be measured by x-ray diffraction. X-ray crystal structure determination and the iridescent colors in nacre, butterfly wings, and beetle exoskeletons are caused by similar phenomena that involves the transmission of visible light. Metals tend to be harder than polymers, ceramics tend to be stronger than polymers, and metals tend to be harder than ceramics. Diamond is a unique material that exhibits metallic bonding. One of its more unusual features is that although it has a very high electrical conductivity, it is a poor conductor of heat.
