What is the Difference Between Krypton and Argon?

Krypton and Argon are both colorless, odorless, and inert gases used in energy-efficient windows to increase their efficiency. However, there are some differences between the two:

1. Density: Krypton is six times denser than Argon and twelve times denser than air, making it more efficient at slowing down or blocking thermal energy than Argon.
2. Particle Size: The particles of Krypton gas are smaller than Argon particles, allowing Krypton to fit better into smaller spaces and crevices.
3. Efficiency: Krypton is generally considered a better insulator than Argon, especially in windows with a 3/8-inch gap between panes. Argon, on the other hand, is more efficient in larger (1/2-inch) gaps between double-pane windows.
4. Cost: Argon is a cheaper alternative to Krypton gas, making it more popular among window companies. Krypton windows tend to be close to 40% more expensive than windows with Argon.

In summary, Krypton is a more efficient insulator than Argon, particularly in windows with smaller gaps between panes. However, Argon is a more cost-effective option and remains the norm for window companies. The choice between Krypton and Argon depends on factors such as energy efficiency, window gap size, and budget.

Comparative Table: Krypton vs Argon

Based on the available information, here is a comparison table between Krypton and Argon:

Krypton and Argon are both noble gases found in group 18 of the periodic table. They are both odorless, colorless, and unreactive. However, Krypton is more expensive and less abundant than Argon, but it is a better insulator. Krypton has a larger atomic radius than Argon, which results in a higher boiling point.
