2. The atomic number is of krypton is 36.

The atomic mass is 83.80.

Krypton is krypton is a gas like neon it is used in lights.

krypton is a nonmetal.

3. Krypton was discovered by William Ramsay and Morris Travers in 1898 by fractional distillation of a mixture of the noble gases. It is a colorless, odorless gas. Krypton is present in the atmosphere to the extent of 1 part in 20 million by volume or 1 part in 7 million by weight. Several compounds of krypton were discovered in 1962 and 1963. Krypton is used alone or with Argon, and Neon. in incandescent bulbs. It emits a characteristic bright, orange-red color in an electric-discharge tube; such tubes filled with krypton are used in lighting airfields because the red light is visible for long distances and penetrates fog and haze to a greater extent than ordinary light. In 1960 the International Commission on Weights and Measures adopted as the length of the standard meter 1,650,763.73 wavelengths of light emitted by the isotope krypton-86.

4. Krypton is used to fill electric lamp bulbs which are filled with a mixture of krypton and argon, and for various electronic devices. Krypton is also used in photographic projection lamps, in very high-powered electric arc lights used at airports and in some strobo-lamps, because it has an extremely fast responds to an electric current.

7.References. The high cost of obtaining krypton from the air has limited its practical applications. Krypton is used in some types of photographic flashes used in high speed photography.  Some fluorescent light bulbs are filled with a mixture of krypton and argon gases.  Krypton gas is also combined with other gases to make luminous signs that glow with a greenish-yellow light. In 1960 the length of the meter was defined in terms of the orange-red spectral line of krypton 86 an isotope of krypton
