Krypton Name: Krypton Symbol: Kr Atomic Number: 36 Atomic Weight: 83.8 amu Krypton in Elemental Form: Krypton as a it is commonly used: State of Matter at Room Temperature: Gas Melting Point Temperature: ‐157.2˚C (115.950005 K, ‐250.95999 ˚F) Boiling Point Temperature: ‐153.4 ˚C (119.75001 K, ‐244.12 ˚F) Density: 3.74 g/cm3 (Density @ 293 K) Color: Colorless Texture: It is a gas Hardness: On the Vickers scale Krypton has a hardness of 340. Malleability: Krypton is a Noble Gas, therefore it can not be shaped. Ductility: Krypton is a Gas therefore it does not fracture. Conductivity: At 0.37 Krypton is a good conductor. Chemical Properties: Flammability: Krypton is a non‐flammable gas when no compressed, however if in a compressed container and heated , it may explode. Photosensitivity: When the Krypton Particles are exposed to Photons they get extremely excited Combustibility: Krypton is not very combustible, when no exposed to high temperatures. However, when you do exposed Krypton particles to high temperatures they have an increased possibility of combustion. Toxicity: Krypton is a non‐toxic gas. Who discovered Krypton? Krypton was discovered by William Ramsay and Morris William Travers. Where was Krypton discovered? Krypton was discovered in Great Britain in 1898. What are the uses of Krypton? Krypton can is usually used for lights, especially fluorescent lights. When was Krypton discovered? 1898 What are a few of the common uses or the historical uses of this element? The main uses of Krypton is for fluorescent lights. How Krypton appears naturally: 1. As a noble gas which is colorless, odorless, and tasteless. Krypton is obtained from liquefied air by distillation. The only basic use of Krypton is to produce lighting. The only problem with Krypton is if you walk into a room full of Krypton you can faint because of the lack of oxygen. Fun facts: 1.
