Miscible with water
Not stable
Chemically unreactive
Chemically very active
Answer is Right!
Answer is Wrong!
The correct answer is C. Chemically unreactive.
Inert gases are elements in group 18 of the periodic table. They are also called noble gases. They are very stable and do not react with other elements. This is because they have a full outer electron shell.
Option A is incorrect because inert gases are not miscible with water. They do not dissolve in water.
Option B is incorrect because inert gases are stable. They do not decay or change into other elements.
Option D is incorrect because inert gases are not chemically very active. They do not react with other elements.
