Known as a chemical element with the atomic number 36, Kr is a noble gas. It is colorless, odorless, tasteless, and can be found in the Earth's atmosphere in trace amounts. Krypton is one of the rare gases that exhibit a rich spectrum of bright and vivid colors, making it useful in lighting and display technologies.
Properties of Kr
1. Chemical Properties:
Krypton is chemically inert and does not readily form compounds with other elements. It has a closed-shell electronic configuration, making it stable and non-reactive under normal conditions.2. Physical Properties:
At room temperature, krypton is a gas. It has a boiling point of -153.22 degrees Celsius and a melting point of -157.36 degrees Celsius. It is denser than air and is often used to fill incandescent light bulbs.Uses of Kr
Krypton's most common application is in lighting, especially in compact fluorescent lamps and high-intensity discharge lamps. It is also used in laser technologies, as well as in industries where a non-reactive atmosphere is required, such as in the production of semiconductors.
In the field of medicine, krypton is used in certain laser surgeries, as well as in diagnostic imaging techniques. Its ability to produce bright and colored light makes it a valuable component in illuminated signs and advertising displays.
Discovery and History
Sir William Ramsay and Morris Travers discovered krypton in 1898 in Britain. They were studying the residue left behind after liquid air had boiled away. The name "krypton" is derived from the Greek word "kryptos," meaning hidden or secret, reflecting the difficulty in detecting this noble gas.
Ramsay and Travers isolated krypton by fractional distillation of liquid air, as krypton boils at a higher temperature compared to other gases in the mixture. This breakthrough led to the identification and understanding of a new element in the periodic table.
