Metals and Metallic Bonds

Resource: http://dl.clackamas.cc.or.us/ch104-08/metallic.htm

We all interact with metals everyday. Metals are a majority of the elements found on the periodic table. Metals are useful for the industrial part of our lives. Also, they make up most of our building foundations and to even our food utensils. Thee properties of metals are usually ductile and malleable. They are also very good at conducting heat and electricity. Metals can be made to alloys as well. With all these things metals can do, how can they really do them? The bonds that hold them together is a great benefactor to this. The electrons are loosely held together which make it almost an ocean of electrons. The heat and electricity pass through metals fairly easy because of their ocean like structure. Also, the hold between the atoms are loose but capable of staying together. This explains the ductile and malleable capabilities of metals. Alloys are a combination of a metal and some other element or elements. One of the ways the alloy is made up is a substitution alloy. It substitutes the other element for places in the original metal, but it will stay about the same structure. Another type is called interstitial alloy. It is when the atoms other than the metal is much smaller and fit in between the holes of the structure of the metal.

Metals are important to human life on earth. We use our metals for most things industrial and others for our common use. Some of the first presumed elements to be found by man were metals. The more we learn about our necessary element, it will help us create new alloys in the future, and it will benefit mankind for the better.
