Question

Which of the following is a chemical property of the noble gases?

A.The boiling points are close together.
B. The melting points are close together.
C. They are unreactive.
D. Mass increases down the group.

Answer 1

They are not reactive .
So C is the answer.

Answer 2

Answer: Option (C) is the correct answer.

Step-by-step explanation:

Chemical property is defined as the property that causes a change in chemical composition of a substance.

For example, toxicity, reactivity, combustibility etc are chemical properties.

Physical property is defined as the property that causes no change in chemical composition of a substance.

For example, melting point, boiling point, mass, volume etc are physical properties.

Therefore, we can conclude that they are unreactive is a chemical property of the noble gases.
