Question

Which is not a noble gas?
(a) helium (b) oxygen (c) neon (d) argon​

Answer 1

$\texttt{Answer}$

||━━━━━━━━━━━━━━━━━━━━━━━||

b) $\blue{{\texttt{Oxygen}}}$

Because :

• The most important chemical property of the noble gases is their lack of reactivity. Helium, neon, and argon do not combine with any other elements to form compounds. Since then, many xenon compounds containing mostly fluorine or oxygen atoms have also been prepared.

• $\purple{{\texttt{Note}}}$ : Noble gases are another family of elements, and all of them are located in the far right column of the periodic table.
