Answers:

1. False : It’s an alloy of two or more chemical elements.
2. True: The chromium gives the steel resistance to “stain” or iron rust. A thin layer of chromium oxide forms on the surface of stainless steel, protecting it from oxygen, which is what causes rust.
3. False: Similarly to steel, stainless steel is a relatively poor conductor of electricity, with a few percent of the electrical conductivity of copper.
4. True: for example stainless steel.
5. True: it also has an atomic number of 26.
6. True: Currently, scientists know of 118 different elements. Some, like gold, silver, copper and carbon, have been known for thousands of years. Others, such as meitnerium, darmstadtium and ununquadium, have only recently been created by scientists.
7. False: about 25% are non-metals. You can identify non metals physically as they are transparent, and on the periodic table they have more electrons on their outer shell (4-8 versus metals’ 1-3).
8. True: This is due to the structure of the elements in this atom.
9. False: Although stainless steel is much more resistant to corrosion than ordinary carbon or alloy steels, in some circumstances it can corrode. It is ‘stain-less’ not ‘stain-impossible’. In normal atmospheric or water based environments, stainless steel will not corrode as demonstrated by domestic sink units, cutlery, saucepans and work-surfaces.
10. True: As part of an Iron-Nickel alloy.
