The noble gas which occurs most abundantly in the atmosphere is:
The noble gas which occurs most abundantly in the atmosphere is:
The correct option is C Ar
Noble gases
Elements in group 18 are called noble gases or inert gases. These elements have stable electronic configuration with completely filled orbitals. Due to this stability, these gases are the least reactive elements in the periodic table and remain in their monoatomic form. They are present in small amounts in atmosphere.
Explanations for wrong answers
(A) Helium (He) is not the the most abundant noble gas in atmosphere. It is around 0.00052 % percent. Therefore, option (A) is incorrect.
(B) Neon (Ne) is not the most abundant noble gas in atmosphere. The percentage of Neon is 0.0018 %. Therefore, option (B) is incorrect.
(D) Krypton (Kr) is not present in the atmosphere. Therefore, option (D) is incorrect.
Explanation of correct answer
(C) Argon (Ar) has a very stable nucleus and is highly inert. Therefore, it is the most abundant noble gas in the atmosphere with a percentage of 0.934 %.
The correct option is (C) Ar
