There is attractive electrostatic forces between the ions which are very strong e.g. sodium chloride ionic lattices. . Give two properties of giant ionic structures. . Isotopes. Isotopes. : atoms of the same element that have different numbers of neutrons. Two isotopes of an element will have the same atomic number, but different mass numbers (and atomic masses). CARBON (above right). SNC2D. Polyatomic Ions. Polyatomic ions are groups of atoms that tend to stay together and carry an overall ionic charge. The ion is typically held together with covalent bonds. The polyatomic ion is capable of bonding with other ions. Many ions are monoatomic BUT. Most ions are polyatomic (>1 atom). 330.07.01b.Names & Formulas - Polyatomic.

Sheet metal forming operations produce a wide range of consumer and industrial products, such as metal desks, appliances, aircraft fuselages, car bodies, and kitchen utensils.. Sheet-metal forming also called press working, press forming or stamping, is among the most important of metalworking processes, dating back to as early as 5000 B.C., when household utensils, jewelry, and other objects were made by hammering and stamping metals such as gold, silver, and copper..

A laxative is a medicine that loosen the bowel contents and encourages evacuation.. Laxatives taken regularly tend to deprive the colon of its natural muscle tone .. Simple constipation is usually relieved by increasing the intake of dietary fiber.. Temperature in metal forming. For any metal, the values of K and n depend on temperature. Strength and strain hardening are both reduced at higher temperatures. These property changes are important because they result in lower forces and power during forming. In addition, ductility is increased at higher temperatures, which allows greater plastic deformation of the work metal. For these reasons the forming processes can be classified as:.
