1.	Which of the following statements is incorrect about noble gases?(a) They are monoatomic(b) They are colourless(c) They are odourless(d) They all have an outer electronic configuration of ns^2np^6This question was posed to me during an interview.The origin of the question is P-Block in portion P-Block Elements of Chemistry – Class 12
Answer» RIGHT option is (d) They all have an OUTER electronic configuration of ns^2np^6 The explanation is: The GENERAL outer electronic configuration for noble gases is ns^2np^6. But, for HELIUM, the outer electronic configuration is 1s^2 as it its atomic number is only 2. All noble gases are monoatomic, odourless and colourless.
