What is krypton?

Answer 1

krypton is present in the air at about 1 ppm. The atmosphere of Mars contains a little (about 0.3 ppm) of krypton. It is characterised by its brilliant green and orange spectral lines. The spectral lines of krypton are easily produced and some are very sharp. In 1960 it was internationally agreed that the fundamental unit of length, the metre, should be defined as 1 m = 1,650,763.73 wavelengths (in vacuo) of the orange-red line of Kr-33.

Under normal conditions krypton is colourless, odourless, fairly expensive gas. Solid krypton is a white crystalline substance with a face-centered cubic structure which is common to all the "rare gases". Krypton difluoride, KrF2, has been prepared in gram quantities and can be made by several methods. krypton is present to a small extent (about 1 ppm by volume) in the atmosphere and is obtained as a byproduct from the liquefaction and separation of air. This would not normally be carried out in the laboratory and krypton is available commercially in cylinders at high pressure.

Krypton is a gaseous chemical element which exists in concentrations of about one part per million in the Earth's atmosphere. Since it exists in low concentrations, it is difficult and expensive to extract, making it rather expensive when it reaches the market. The most common use of krypton is in lighting, since the gas glows a very bright white when it conducts current. Many so-called "neon" signs are actually made with krypton in colored tubes which glow as the gas turns into plasma. The element with 'urine' is Phosperous.

Answer 2

Several krypton uses are:
- filling gas for bulbs in special high speed Photography
- magnetic resonance imaging
- calorimeters for particles physics
- lasers
Uses are limited because krypton is rare and very expensive.

Answer 3

Krypton is a chemical element with the symbol Kr and atomic number 36. It is a colorless, odorless, tasteless noble gas that is found in small quantities in the Earth's atmosphere. Krypton is used in lighting, such as in fluorescent lamps and flashlights, and in certain types of lasers.

Answer 4

Krypton is a gas, practically unreactive, member of the group 18 of the Periodic Table (noble gases).

Answer 5

The atmosphere contains a small amount of krypton.

Answer 6

Krypton is a type of gas that's used in some types of photographic flashes used in high speed photography.

Answer 7

used in lassers

Answer 8
