Rare gases are suitable because they?

A. are monoatomic
B. form ions easily
C. have duplet or octet electronic configuration in the outermost shells in their atoms
D. are volatile gases

Correct Answer:

Option C – have duplet or octet electronic configuration in the outermost shells in their atoms

Explanation

Rare gases are stable because they have duplet or octet electronic configurations in the outermost shells in their atoms, as a result, they don’t go into solution easily. option A, B, D are not because they go into solution easily (unstable)
