The chemical symbol for krypton is Kr. The melting point for krypton is 115.79 degrees Kelvin or -156.36 degrees Celsius or degrees Celsius. The boiling point of the krypton is 119.93 degrees Kelvin or -152.22 degrees Celsius or degrees Celsius.
Uses of krypton
Krypton is a colorless, odorless and tasteless gas. It is one of the 6 noble gases, that is, with very low chemical reactivity and is present in small quantities in the Earth’s atmosphere. It was discovered in 1898 by Sir William Ramsay and Morris Travers while experimenting with air. It is considered as an expensive and rare gas. However, it has many common uses, of which most people are not aware. If you have ever wondered what krypton is for , here is a list of its possible uses:
- Krypton bulbs are used in photography for some applications as they produce white light under certain conditions. Generally used in high speed photographic flashes.
- This white color is used in colored gas pipes to create an effect similar to that of a neon sign .
- Krypton is used in the production and use of the krypton fluoride laser, which is being used in nuclear fusion research. Its use is also frequent in high power laser shows.
- The krypton is mixed with argon to fill the fluorescent lamps. This makes them more energy efficient by reducing the power they need. Unfortunately, its use makes this type of bulb more expensive and reduces light emission. Krypton is used in conjunction with xenon in bulbs to reduce melting of the filament and allow it to operate at higher temperatures.
- An isotope of krypton is used in medical examinations of the airways.
- A measurement of the wavelength emitted by an isotope of krypton was used to define the distance of one meter between 1960 and 1983.
Atomic properties of krypton
The atomic mass of an element is determined by the total mass of neutrons and protons that can be found in a single atom belonging to this element. As for the position where to find the krypton within the periodic table of the elements, the krypton is in group 18 and period 4. The krypton has an atomic mass of 83,798 u.
The electronic configuration of the krypton is [Ar] 3d10 4s2 4p6. The electronic configuration of the elements, determines the form in which the electrons are structured in the atoms of an element. The khripton’s atomic radius or Bohr radius is 88 pm, its covalent radius is 110 pm, and its Van der Waals radius is 202 pm. The krypton has a total of 36 electrons whose distribution is as follows: In the first layer it has 2 electrons, in the second it has 8 electrons, in its third layer it has 18 electrons and in the fourth one, 8 electrons.
