Which of the following is not true in regard to noble gases?

BThese elements tend to gain or lose electrons easily
CThese elements are found in the last column (Group 18) on the periodic table
DThese elements have full outermost shells

Verified Answer :

the answer is b. elements react because they want to gain a full outer shell of electrons (or in other words, to have 8 valence electrons). because noble gases already have 8 valence electrons, they don't need to gain any more/won't give them up easily.

Answer: The correct answer is option (B).

Explanation:

Noble gases are stable gases and have following characteristics:

  • Gases with complete outermost shell.
  • Gases which are inert in nature.
  • Found in the last group of the periodic table that is group 18.
  • Generally are non reactive,
  • Occurs in mono-atomic gases.
