Which of the following is NOT a property of noble gases (group 0 elements)?Low boiling pointGas at room temperatureGood thermal conductorsInert or unreactive

To determine which of the listed options is NOT a property of noble gases (group 0 elements), let's analyze each property:

1. Low boiling point: Noble gases have relatively low boiling points compared to many other elements. This is true.

2. Gas at room temperature: All noble gases are indeed gases at room temperature. This is also true.

3. Good thermal conductors: Noble gases are not known for being good thermal conductors; in fact, they are poor conductors of heat and electricity. This statement is NOT true.

4. Inert or unreactive: Noble gases are known for their lack of reactivity due to having a complete valence shell of electrons. This statement is true.

Final Answer

The option that is NOT a property of noble gases is Good thermal conductors.
