Correct Answer - Option 4 : Chemically unreactive

The correct answer is Chemically unreactive.

  • Inert gases are Chemically unreactive.
    • An inert gas is a gas that does not undergo chemical reactions under a set of given conditions.
    • The noble gases often do not react with many substances and were historically referred to as inert gases.
    • The group 18 elements include - 
      • helium, neon, argon, krypton, xenon, and radon.
    • But recent studies have shown reactive compounds of xenon, krypton, and radon. 
  • Hence, option 4 is correct.

  • The IUPAC is responsible for maintaining the periodic table.
  • Nobel gas :
    • Noble gas, any of the seven chemical elements that make up Group 18 (VIII a) of the periodic table. 
    • The noble gases are colourless, odourless, tasteless, nonflammable gases.
    • They traditionally have been labelled Group 0 in the periodic table because for decades after their discovery.
    • it was believed that they could not bond to other atoms, that is, that their atoms could not combine with those of other elements to form chemical compounds.
