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.
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.
