Crystal Structures

Solids are present all around us. They have different properties and applications. Diamond and graphite are two well-known solids. Diamond is the hardest material in the world and is used in making jewelry. Graphite on the other hand is soft. The lead of your pencil is graphite. Why are they so different in appearance and properties despite the fact they are chemically the same? Both are allotropes of carbon. The answer lies in the structure, the way constituent particles are arranged in the solids.

There are three sets of sketches below, showing the same pure molecular compound (carbon monoxide, molecular formula CO) at three different temperatures. The sketches are drawn as if a sample of carbon monoxide were under a microscope so powerful that individual atoms could be seen. Only one sketch in each set is correct. Use the slider to choose the correct sketch in each set. You may need the following information: melting point of CO: -205. C boling point of CO: -192. °C 210. °C -152. "C 200. "C
