Question

Neon and Argon are both members of the group called noble gasses. What properties do noble gasses have that make them unique?Group of answer choicesThey emit odor and have bright color in their natural stateThey are highly reactiveThey are nonreactiveThey combine easily with other elements

Answer 1

The correct answer should be that they are non reactive. Rather they do not react with other substances easily. This is because all noble gases have full valence electron shells. This makes then achieve the octet structure that makes them most stable. Since they are already very stable, they will no longer react to form compounds easily. However, through physical processes such as mixing xenon with fluorine under heat, irradiation or electrical discharge we are able to make xenon difluoride which is a halogen compound that is relatively stable.
