How many atoms are in the primitive unit cell for diamond?

Diamond is a solid form of pure carbon with its atoms arranged in a crystal. Solid carbon comes in different forms known as allotropes depending on the type of chemical bond. The two most common allotropes of pure carbon are diamond and graphite. In graphite the bonds are sp orbital hybrids and the atoms form in planes, with each bound to three nearest neighbors 120 degrees apart. … http://hyperphysics.phy-astr.gsu.edu/hbase/Solids/sili2.html crystal lightning actress
