correct the mistakes in this statement
A vacancy is a point defect thatoccurs when an atom is missing from a lattice position. A perfectmetal crystal would exhibit ductile behavior. Amorphous crystalshave long range order which can be measured by x-ray diffraction.X-ray crystal structure determination and the iridescent colors innacre, butterfly wings, and beetle exoskeletons are caused bysimilar phenomena that involves the transmission of visible light.Metals tend to be harder than polymers, ceramics tend to bestronger than polymers, and metals tend to be harder than ceramics.Diamond is a unique material that exhibits metallic bonding. One ofits more unusual features is that although it has a very highelectrical conductivity, it is a poor conductor of heat.
