Which of the following is not a characteristic of a noble gas?
They exist in nature as single atoms.
They always have fewer than 8 valence electrons.
They follow either the duet rule or the octet rule.
They are not very reactive.

Noble gases are inert and unreactive elements that have full octet configurations, except for helium, which follows the duet rule. They exist as single atoms and have 8 valence electrons, making them very stable.

Explanation:

Noble gases have the most stable configuration with a full octet, making them very inert and unreactive compared to other elements. They follow the octet rule, except for helium, which adheres to the duet rule as it aims for 2 valence electrons. These gases typically exist as individual atoms and have 8 valence electrons.
