Question

The noble gases do not usually form chemical compounds because:

• A. they have very stable nuclei
• B. they are not polar
• C. the bonds between their atom are very strong
• D. they already have completely filled valance electron shell

Answer 1

Answer: (D)

they already have completely filled valance electron shell

Noble gases has completely filled outer shell/valence shell. Due to this reason they are very stable and and do not react with other elements. Hence noble gases are called inert gases means they do not react with other elements to form chemical compounds.
