Question 44

Neon will have poor thermal and electrical conductivity.

Neon (Ne), being a noble gas located in Group 18 of the periodic table, exhibits poor thermal and electrical conductivity due to its complete electron shell and lack of free-moving charge carriers.

A) Poor thermal conductivity

This option is correct as noble gases like neon have low thermal conductivity. Their atomic structure results in minimal interaction between atoms, leading to reduced heat transfer capabilities.

B) Good electrical conductivity

This option is incorrect because neon does not have free electrons that can move freely, which is essential for electrical conductivity. Noble gases are generally non-conductive in their gaseous state.

C) Poor electrical conductivity

This option is correct as neon is an inert gas with a full valence shell, preventing it from easily conducting electricity. The absence of free charge carriers is a characteristic trait of noble gases.

D) Good thermal conductivity

This option is incorrect as neon, like other noble gases, has poor thermal conductivity. Its atomic structure does not allow for efficient energy transfer, which is why it does not perform well in terms of thermal conductivity.

Conclusion

The correct answer illustrates that neon exhibits both poor thermal and electrical conductivity due to its noble gas characteristics. Options A and C accurately represent these properties, while options B and D fail to acknowledge the inherent lack of conductivity associated with neon and other noble gases.
