Xenon

​ = Xenon = By: David


 * Atomic Number: ** 54


 * Protons: ** 54 


 * Electrons: ** 54 


 * Neutrons: ** 77


 * Average Atomic Mass: ** 131.293


 * Isotopes: ** There are nine stable isotopes: Xe-124, Xe-126, Xe-128, Xe-129, Xe-130, Xe-131, Xe-132, Xe-134, and Xe-136.

​
 * Discovery: ** Xenon was discovered by William Ramsay and Morris Travers in 1898, by studying liquefied air.
 * Name: ** ​​The noble gas's name comes from the Greek word "xenos," meaning "strange." ​


 * Uses: ** ​Xenon is used mostly for lighting, like flash cameras or "high-intensity" lamps, which is used in movies. In car headlights, xenon was found to be brighter and more efficient. A xenon light bulb lasted about 2000 hours compared to a regular 400-hour halogen bulb. It is also found in electron tubes, stoboscopic lamps, and bactericidal lamps.


 * Interesting Facts ** : ​Usually colorless, it turns blue when its atoms are excited. Metallic xenon exists. It's classified as a noble gas, because it's outermost energy level is full and is very unreactive with other elements.
