Rare gases are stable 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

The correct answer is C. have duplet or octet electronic configuration in the outermost shells in their atoms

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, Dare not because they go into solution easily (unstable)
