(5) ......... is a good conductor of electricity.
(a) Bromine (b) Iodine (c) Graphite (d) Sulphur
Answers
Graphite
Its structure is the main reason for this property. Each carbon atom in graphite is directly linked to only three carbon atoms through covalent bonds. ... These free electrons make graphite a good conductor of electricity and also a good lubricant.

Answer:
The correct answer is (c) Graphite.
Explanation:
Graphite is a good conductor of electricity due to its unique atomic structure, which consists of flat sheets of carbon atoms arranged in a hexagonal lattice. Each carbon atom in graphite is covalently bonded to three other carbon atoms, creating a strong and stable network.
Furthermore, graphite has a delocalized electron cloud that allows electrons to move freely throughout the structure, making it an excellent conductor of electricity. This property makes graphite a widely used material in electrical applications, such as in batteries, electrical contacts, and as a component in electronic devices like computer chips.
In contrast, Bromine, Iodine, and Sulphur are not good conductors of electricity because they are non-metals and lack the delocalized electrons needed to conduct electricity.
