WebJul 8, 2010 · Diamond is a molecular and crystal structure visualization software. It only draws nice pictures of molecular and crystal structures, but also offers an extensive set of functions that let you easily model any arbitrary portion of a crystal structure from a basic set of structural parameters (cell, space group, atomic positions). WebLearn about differences in the molecular structures of two forms of carbon—diamond and graphite—in this video from NOVA: Treasures of the Earth: Gems. Although diamonds and graphite are both made of pure carbon, the way the atoms link together is very different. In diamonds, one carbon atom is bonded with four others to create a dense, cage-like …

WebTranscribed Image Text: 1.) a.) GaAs (GaAs) has the “zinc blende" crystal structure with a lattice constant of 5.653 Å. Zinc blende is the diamond cubic structure, with atoms of one type (Ga) on the vertices and faces, and atoms of the other type (As) in the internal tetrahedral sites. Determine the density of GaAs from the crystal structure. WebThe hardness and density of diamonds can be explained by their crystal structure.Each carbon atom is surrounded by four other carbon atoms in a regular tetrahedron. Each of these carbon atoms is then attached to three other carbon atoms (plus the original atom), and that pattern continues to form a single, giant molecule held together by covalent bonds. images of harris hawk https://thewhibleys.com
