Krypton (Kr)
Krypton (Kr) is a colorless, odorless, and tasteless noble gas (atomic number 36) found in trace amounts in the atmosphere. It is chemically inert but is used extensively in lighting, high-speed photography, and energy-efficient insulated windows due to its low thermal conductivity and unique spectral properties.
Key Details:
Chemical Formula: Kr
Description: A noble gas with a boiling point of −153.4°C and a density of 0.003425 g/cm3. Krypton is typically extracted from liquid air through fractional distillation. Although largely unreactive, it can form a few compounds, such as krypton difluoride (KrF2).
Common Uses:
- Lighting: Fills fluorescent lamps, incandescent bulbs, and high-speed photography flashes.
- Lasers: Used in krypton fluoride lasers for nuclear fusion research.
- Insulation: Used in double-pane windows for superior thermal efficiency.
- Scientific / Medical: Used in leak detection and occasionally in medical applications.
