Alloying is a very good method of improving the properties of a metal. Alloys are mixtures of metals with _________ .

• A. non-metals
• B. metals
• C. either metals or non-metals can be used
• D. neither metals nor non-metals can be used

Answer 1

The correct option is C either metals or non-metals can be used

The properties of any metal can be changed if it is mixed with some other substance (metal and/ or non metal) to form an alloy. The substance added may be a metal or a non-metal.

For example, when iron is alloyed with chromium, molybdenum, nickel (metals) and carbon (a non-metal) a hard substance called as Stainless Steel is formed.
