Answer 2

The odd one out among them is argon.

• All the elements given are reactive gases in a natural state but argon is the odd one out because it is an inert one.
• The other gases which are oxygen, hydrogen and chlorine are gases that have high reactivity.
• Oxygen has a valency of 2-, hydrogen has a valency of 1+ and chlorine has a valency of 1-.
• Argon does not have a valency as its outer orbital is fully filled which cannot gain or donate an electron to combine with any other atom.
