Homework #5 week two semester two

1. An alloy is a solid combination of atoms of two or more elements.
2. Two examples of alloys I use regularly are 14 karat gold (in jewelry) and stainless steel (refrigerator door).
3. The nonmetal that is a component of both steel and stainless steel is Carbon ( C)
4. The formula, use, and an important physical properties of an alloy that I also a well-defined compound:
1. Cr₃Pt (chromium-platinum)
2. Used to form the basis of some commercial razor blade edges.
3. It has a constant, definite ratio of metallic atoms
5. The periodic table location of elements that behave as semiconductors is in the metalloid section because they are not fully conductive like metals, yet they aren’t completely nonconductive like nonmetals.
6. Three elements that are commonly used for doping semiconductors are Phosphorous, arsenic, and Aluminum
7. The primary uses of the products of semiconductor technology are as transistors and integrated computer circuits.
