Question 44

Neon (Ne) has poor thermal conductivity and poor electrical conductivity.

Based on its position in the periodic table as a noble gas, neon exhibits poor thermal conductivity and poor electrical conductivity. These properties are characteristic of noble gases, which are generally inert and do not conduct electricity well.

A) Poor thermal conductivity

This option is correct because noble gases, including neon, are known for their low thermal conductivity. Their atomic structure does not allow for efficient transfer of heat, making them poor conductors in this regard.

B) Good electrical conductivity

This option is incorrect as noble gases like neon do not have free electrons available for conduction. Their complete electron shells result in a lack of electrical conductivity, which is a fundamental property of inert gases.

C) Poor electrical conductivity

This option is correct because neon, like other noble gases, does not conduct electricity well. The absence of free-moving charge carriers means that neon has poor electrical conductivity, aligning with its classification in the periodic table.

D) Good thermal conductivity

This option is incorrect since noble gases, including neon, do not exhibit good thermal conductivity. Their atomic structure contributes to their inefficiency in transferring heat, which is contrary to what this option suggests.

Conclusion

Neon is characterized by poor thermal and electrical conductivity due to its status as a noble gas. The correct properties, poor thermal conductivity and poor electrical conductivity, reflect the inherent nature of noble gases, while the other options fail to align with these defining characteristics. Thus, A and C accurately represent the properties of neon.
