Question 83

Which statement avoids the common overclaim that noble gases can never react?

  1. They react more strongly than alkali metals.
  2. They always react rapidly at room temperature.
  3. No noble-gas compound can exist.
  4. They are weakly reactive, not absolutely unable to react.Bonne réponse

Explication

Noble gases are far less reactive than most families, but low reactivity is not an absolute ban on compound formation. Claiming that reaction is impossible under every condition turns a useful general pattern into a false universal rule.
