These will be our atoms and ions. There are also two square plastic blocks with holes drilled in them. These will be the bases. Notice that one has a circular sticker and the other a semicircular sticker. There are also a number of square paper templates with holes punched in them. Each has either a circle or semicircle in the corner and a letter to identify it. There is also a long plastic tube with metal rods in it. As s e mbling the s tructure bas e . Instructions for assembling each solid state base appear on the ensuing pages. In each case, a paper template is placed on top of one of the bases, with the circle or semicircle aligned. The metal rods are then inserted into specific holes in the template, as instructed. The structure is then built up, layer by layer. Taking a mode l apart. To take a model apart, invert the structure and allow the spheres to slowly slide off the rods. Try to make sure the spheres do not roll away. Remove the rods by grasping near the base and pulling without bending or wiggling. Ins tructions for as s e mbling the s olid s tate s tructure s . Instructions for each of the structures in this lab are given on the ensuing pages. For each structure, pictures are reproduced from the instruction manual that accompanies the model kits. They include a picture of the template in the upper right hand corner and the pattern of holes that are used on that template in the upper left hand corner. Next to each hole in the pattern is a number, www.webassig encheml1/lab_7/manual.html 2/10 4/15/13 Lab 7 - Solid State M odeling which corresponds to a layer of atoms. Building the layers in numerical order forms structures. Usually the top layer of the structure is a repeat of layer number 1, and is referred to as layer 1'. You will notice that some of the numbers are black and others are white. The black and white numbers correspond to different color spheres, as given by the key at the bottom left c...
