Question

German Silver does not constitute:
A.Copper
B.Nickel
C.Zinc
D.Silver

Answer 1

Hint: To answer this question, you should recall the concept of alloys as well as the composition of German silver. It is named so because of its silver-white colour.

Complete step by step answer:
The meaning of the term ‘alloy’ is a substance formed from the combination of two or more metals. Alloys can also be formed from combinations of metals and other elements. The properties exhibited by alloys are often quite different from the properties of its components. It is not uncommon for alloys to have greater strength and hardness when compared to pure metals. An example of an alloy is red gold, which is produced by alloying copper and gold together.
German silver or nickel silver is the type of an alloy mainly made up of copper, zinc and nickel and is occasionally found to contain trace amounts of tin and lead. It is known for its toughness, hardness and corrosion resistance. From its name, some people mistakenly think that one of its constituents is silver. The name is due to its silver-white colour.

Hence, the correct option is D.

Note:
The difference between an element, compound, and mixture. Elements are substances that are made from a single type of atom. An element cannot be broken down into any other substance. Examples include carbon, sulfur, oxygen, iron, copper, aluminium. Compounds are substances that are formed from atoms of different elements that are connected by chemical bonds. The compounds can be separated into its constituent elements by a chemical reaction. Common examples are water, sodium chloride, methane. A mixture is formed through simply mixing of elements or compounds. No new chemical bonds are formed. Mixtures can be separated using physical techniques.
