In this article, we shall study to solve problems to calculate the atomic radius, the distance between atoms in the unit cell and to decide the type of crystal structure. A naturally occurring gold crystallizes in face centred cubic structure and has a density of Calculate the atomic radius of gold. Sodium metal crystallizes in the bcc structure with an edge length of unit cell 4. Calculate the atomic radius of sodium metal. Niobium crystallizes in bcc structure and has a density of 8. Calculate its atomic radius, if its atomic mass is Sodium metal crystallizes in the body-centred cubic unit cell.

This section deals with the geometry of crystaline systems. These could describe how metal atoms pack when they form metallic solids, or how ions pack when they form ionic crystals. We will look at the ionic structures in the next section, and here focus on the generic unit cell and it's application to metallic structures. There are 7 types of unit cells figure In this class we will only focus on the cubic unit cell , and there are three types of cubic cells that you need to be familiar with, and these are represented in figure In this class we will only look at cubic systems, and will identify 3 types of cubic unit cells figure. The cubic unit cell is the smallest repeating unit when all angles are 90 o and all lengths are equal figure Each cubic cell has 8 atoms in each corner of the cube, and that atom is shared with 8 neighboring cells. In the Body Centered Cubic Cell BCC there is an additional atom in the center of the cube, and in the face centered cubic cell, an atom is shared between two unit cells along the face.

For the body center atoms, the contribution of that atom is a total of a total atom. The per cent fraction of edge length not covered by atom is :. At what angle for the first - order diffraction, spacing between two p

Most solids form with a regular arrangement of their particles because the overall attractive interactions between particles are maximized, and the total intermolecular energy is minimized, when the particles pack in the most efficient manner. The regular arrangement at an atomic level is often reflected at a macroscopic level. In this module, we will explore some of the details about the structures of metallic and ionic crystalline solids, and learn how these structures are determined experimentally.
