The noble gases, such as helium and neon, are a group of chemical elements with very similar properties:

• Generally unreactive: They are known for being extremely stable and unreactive due to their full valence electron shells.
• Colorless, odorless, and tasteless: In their natural state, they are gases that are not easily detectable by human senses.
• Monoatomic: They exist as single, unbonded atoms rather than forming molecules with themselves or other elements.
• Low boiling points: They exist as gases at room temperature and have very low boiling points, meaning they easily transition to the gaseous state.

The noble gases include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og).
