+The periodic table of the elements displays 98 elements which can be found in nature, and the majority of them are classified as metals.  Metals have many important properties, but here we will focus on their electrical conductivity and physical deformability.
+In nature, almost all metals are found chemically bonded to other elements.  In most cases, in order for the metals to be useful, these chemical bonds must be broken.  That process is called smelting.  Once that process is finished, the metals can form new chemical bonds, which we call corrosion.
+In some cases, blending different elements makes the result more valuable than the pure element. These materials, called alloys, can be stronger, more flexible, or more resistant to corrosion than the metals that make up the alloy.
