group 0 Flashcards
(15 cards)
What are Group 0 elements commonly known as?
Noble gases.
List the noble gases in order from top to bottom of Group 0.
Helium, neon, argon, krypton, xenon, radon.
What is the general electronic configuration of noble gases?
They have full outer electron shells; helium has 2 electrons, others have 8.
Why are noble gases chemically inert?
Because they have full outer shells, making them stable and unreactive.
What type of molecules do noble gases form?
They exist as monatomic gases (single atoms).
What is the physical state of noble gases at room temperature?
They are colorless, non-flammable gases.
How do boiling points change as you go down Group 0?
Boiling points increase.
Why do boiling points increase down Group 0?
Because atoms become larger with stronger intermolecular forces, requiring more energy to separate them.
What is the trend in density as you move down Group 0?
Density increases.
What is helium commonly used for?
Filling balloons and airships, as it is lighter than air and non-flammable.
Why is argon used in light bulbs?
Because it is inert and prevents the filament from oxidizing.
Which noble gases are used in advertising signs?
Neon, argon, and xenon.
What is the boiling point of helium?
Approximately -269°C, the lowest of all elements.
What is the electronic configuration of neon?
2,8.
Why don’t noble gases form compounds easily?
Because their full outer electron shells make them stable and unreactive.
