Metallic element gives up valence electrons to the nonmetallic elements. Attractive forces from positive and negative ions Ceramic materials: high melting temperatures‚ hard‚ poor conductors Covalent Bonding Electrons are shared between adjacent atoms resulting in stable electron configurations. Many nonmetallic elemental molecules are covalently bonded. Polymeric materials have this bond. Crystal Structure Describe the crystal structure using an array of points or lattice.

MATERIALS CONTROL: PROCUREMENT AND EXTERNAL TRANSPORTATION I. MATERIALS MANAGEMENT MATERIALS – is one of the principal “m’s” of industry‚ worry controllers‚ annoy sales managers‚ plague purchasing agents‚ haunt production managers‚ and harass stock-keepers. MATERIAL MANAGEMENT – is a continual struggle between too much and too little‚‚ too soon and too late. In sum‚ materials management is concerned with controlling the kind‚ amount‚ location‚ movement‚ and timing of the various commodities

inspection may be combined w/ the handling. 2. Handling may be use as a storing device ‘Storing on the move”- the term applied to storage on moving conveyors. Actually‚ any conveyor that holds waiting material‚ serves as both transport and storage device. A handling rack holding banks of material or an endless conveyor carrying parts form storage to production are examples. 3. Handling may serve as a pacesetter Conveyors moving either continuously or intermittently can pace the operation
