SS1 Physics Crystal Structure __________________ C Mendel Lattice 1. A crystal is a solid composed of atoms, ions, or molecules arranged in a pattern that is periodic in HOW MANY DIMENSIONS? A 3 B 1 C 2 D 4 D Bravais Lattice 7. An extra lattice point is centered in each of two opposing faces of the cell. A body-centered B end-centered C face-centered simple D primitive unit cell 2. It is the smallest part of a crystal that, if repeated regularly by translation in three dimensions, creates the whole crystal. 8. An extra lattice point is centered in the exact middle of the cell. A cell plant cell A face-centered C unit cell D cellular body C simple primitive unit cell 3. It is a periodic array of structural units, such as atoms or molecules. It can be constructed by the infinite repetition of these identical structural units in space. A Ionic Crystal B Covalent Crystal C Metallic Crystal D 4. The unit cell of a crystal is defined by Ideal Crystal A crystal's growth time shape B crystal's C crystal's texture D points crystal's 9. Nigerian Tulip International Colleges B lattice B body-centered D end-centered It contains exactly one lattice point. A non-primitive unit cell B body-centered unit cell C face-centered unit cell D primitive unit cell 10. It tends to be densely packed. Typically, only one element is present, so all atomic radii are the same. It has the simplest crystal structures. A Metallic Crystals B Ideal Crystals C Ionic Crystals D Covalent Crystals 11. It is an ordered array of points describing the arrangement of particles that form a crystal. 5. He showed that crystals could be divided into 14 unit cells. A structure B vertices D lattice A Auguste Bravais B Jude Bravais C point C Ralp Bravais Gabriel Bravais 12. An extra lattice point is centered in every face of the cell. D 6. An infinite array of discrete points with an arrangement and orientation that appears exactly the same, from any of the points the array is viewed from. A Same Lattice B Infinite Lattice [1] A end-centered B face-centered C body-centered D zero-centered cell
