6.3 Group 0: The Noble Gases

Cards (24)

  • The noble gases are called "noble" because they are highly unreactive
  • How many noble gases are there in the periodic table?
    6
  • Noble gases are colorless and odorless gases at room temperature.

    True
  • Noble gases have relatively high melting/boiling points compared to other Group 0 elements
  • What is the primary reason noble gases are unreactive?
    Full outer electron shells
  • Match the noble gas with its electron configuration:
    Helium ↔️ 1s^2
    Neon ↔️ 2s^2 2p^6
    Argon ↔️ 3s^2 3p^6
    Krypton ↔️ 4s^2 4p^6
  • The electron configuration of noble gases is the key to understanding their high stability and low reactivity
  • The noble gases have full outer electron shells, which makes them highly stable.

    True
  • Which group of elements in the periodic table is known as the noble gases?
    Group 0
  • Noble gases are unreactive because they have full outer electron shells.

    True
  • Noble gases have extremely low reactivity
  • Order the noble gases from highest to lowest melting/boiling points:
    1️⃣ Radon (Rn)
    2️⃣ Xenon (Xe)
    3️⃣ Krypton (Kr)
    4️⃣ Argon (Ar)
    5️⃣ Neon (Ne)
    6️⃣ Helium (He)
  • Why are noble gases difficult to detect visually?
    They are colorless
  • What is the appearance of noble gases at room temperature?
    Colorless and odorless
  • Match the noble gas with its electron configuration:
    Helium ↔️ 1s^2
    Neon ↔️ 2s^2 2p^6
    Argon ↔️ 3s^2 3p^6
    Krypton ↔️ 4s^2 4p^6
  • The full outer electron shells of noble gases result in their unreactivity and high stability
  • What property of helium makes it suitable for cryogenics?
    Low boiling point
  • Which noble gas is used in photography flash lamps?
    Xenon
  • Arrange the noble gases in order of increasing atomic number:
    1️⃣ Helium
    2️⃣ Neon
    3️⃣ Argon
    4️⃣ Krypton
    5️⃣ Xenon
    6️⃣ Radon
  • What makes noble gases highly stable and unreactive?
    Full outer electron shells
  • Match the noble gas with its primary use:
    Helium ↔️ Cryogenics
    Neon ↔️ Advertising signs
    Argon ↔️ Welding
    Krypton ↔️ Laser technology
  • Argon is used in welding to shield against oxidation
  • Match the noble gas with its relevant property:
    Helium ↔️ Inertness
    Neon ↔️ Bright red light
    Argon ↔️ Shields against oxidation
    Krypton ↔️ Emits different wavelengths
  • Noble gases are unreactive due to their full outer electron shells.
