Question

Copper has the structure of a typical metal. It has a lattice of positive ions and a “sea ‘of mobile electrons.
The lattice can accommodate ions of a different metal.
Give a different use of copper that depends on each of the following.

(i) Ability of the ions in the lattice to move past each other (1m)

(ii) Presence of mobile electrons (1m)

(iii) Ability to accommodate ions of a different metal in the lattice (1m)

Answer 1

Answer:

2nd one is the write answer

Answer 2

Properties of Copper

Explanation:

1. The ability of ions in lattice to move provide the property of conductivity to copper; due to this attribute, copper, can act as an excellent conductor and transmit electricity and heat efficiently.
2. The presence of mobile electrons increases its property of conductivity as free mobile electrons contribute to transmitting electric current properly and at a fast rate.
3. Its property of accumulating ions of other metals can help copper to make alloy easily, or in simple words, we can make alloys easily by using copper due to this property, for example, Brass = copper + zinc.
