Question

The two main metals in bronze are:
(a)- Copper and Zinc
(b)- Copper and Lead
(c)- Copper and Nickel
(d)- Copper and Tin

Answer 1

Hint: Bronze is an example of an alloy so, there are two metals in it. The first metal of the bronze belongs to group 11 of the d-block and the fourth period, therefore, its atomic number is 29, and the second metal belongs to group 14 of the p-block and the fifth period, therefore, its atomic number is 50.

Complete answer:
Some metals don't have all the properties, so they are mixed with other metals to form an alloy that has more properties than a single metal. Bronze is one of the examples so there are two metals in it. The first metal of the bronze belongs to group 11 of the d-block and the fourth period, therefore, its atomic number is 29, and the second metal belongs to group 14 of the p-block and the fifth period, therefore, its atomic number is 50. Therefore, the two metals are copper and tin.
In bronze, the main metal is copper, and tin's amount is only 12-12.5%, and many other metals are also present in small ratios like aluminium, nickel, zinc, etc and some other like arsenic, silicon, phosphorus is also present.
All these metals increase the properties like strength, ductility, machinability, etc.
In the bronze age, bronze was the hardest metal known.

Therefore, the correct answer is an option (d)- Copper and Tin.

Note: Bronze is used to make stainless steel, boats, ships, submerged bearings, etc. In the early ages, it was used for making coins. It is also used in electrical connectors and springs.
