7. What is an ally?
An alloy is a solid combination of atoms of two or more metals.
8. Give examples of two alloys you use regularly
Brass, Steel, Rose gold
9. What nonmetal is a component of both steel and stainless steel
Carbon
10. Give the formula, use and important physical property of an alloy that is also a well defined compound.
Steel is made up of Iron (Fe) and Carbon (C.) Steel has 99% iron, and 1% Carbon. Steel doesn't rust like normal iron. With a high-carbon steel is hard but brittle; with a low- to medium- carbon steel can be welded (Joined together by heating) and shaped. Steel is used in automobile and airplane parts, kitchen utensils, plumbing fixtures and architectural decoration.
11. Describe the periodic table location of elements that behave as semiconductors.
the semiconductors are elements that are not like the non metals that don't conduct any electricity, and they aren't like the metals which always conduct electricity, they are in the middle. They are the metalloids.
12. List three elements commonly used for doping semiconductors
Phosphorus, arsenic, aluminum
13. What is the primary use of the product of semiconductor technology?
Transistors and integrated circuits used in computers and other electronics.
