Used in nickel-cadmium batteries. Also in electroplating steel and in the manufacture of berings. Its compounds are found in paint pigments and a wide variety of intense colors. Boiling cadmium gives off a weird, yellow-colored vapor that is poisonous. Obtained as a by product of zinc refining. boRius1DYdQ Cadmium
Scottish chemist Sir William Ramsay and his assistant English chemist Morris Travers discovered krypton in 1898 in London.

They found krypton in the residue left from evaporating nearly all components of liquid air.

William Ramsay was awarded the 1904 Nobel Prize in Chemistry for discovery of a series of noble gases, including krypton. From the Greek word kryptos, hidden 48 1817 Friedrich Strohmeyer Germany Somewhat confusingly, from the Latin word "cadmia" meaning "calamine" (zinc carbonate, ZnCO3) and from the Greek word "kadmeia" with the same meaning.

Krypton is considered to be non-toxic
When ionized, krypton gas emits bright white light
Krypton is used in certain photographic flash lamps for high-speed photography.

Krypton-83 has application in magnetic resonance imaging (MRI) for imaging airways.

Krypton is used as a filling gas for energy-saving fluorescent lights and as an inert filling gas in incandescent bulbs.
