1.9 Group 0

• Noble Gases have full outer electron shells, making them extremely inert
• Match the Noble Gas with its key property:

  Helium ↔️ Lowest boiling point

  Neon ↔️ Used in neon signs

  Argon ↔️ Most abundant in air

  Radon ↔️ Radioactive, used in therapy
• Noble Gases are stable because they have full outer electron shells.
