STATE, BOILING AND MELTING POINTS
- Xenon is a gas at 298K. (76.7 degrees in Fahrenheit)
- Melting Point: 161.36 K (-111.79°C or -169.22°F)
- Boiling Point: 165.03 K (-108.12°C or -162.62°F)
- These are both freezing temperatures

WHERE AM I?
- Xenon is present in the atmosphere at a minimum
- It is present at 0.1 per million in the atmosphere
- It is extracted from liquid in air
- Can be used in lamps and electron tubes
- It is a rare element along with several of the other noble gases

DISCOVERY
- Was founded by Sir William Ramsay (Scottish) and Morris M. Travers (English)
- Founded on July 12, 1898 (around the same time as neon and krypton)
- Founded in London

HOW IT WAS FOUND
- It was studied through liquified air
- They found a residue of it, after distillation.
- It was a surprise to be found

QUOTE ON THE FOUNDING OF XENON
- "krypton yellow appeared very faint, the green almost absent.
- Several red lines. Is this pure krypton at a pressure which does not bring
- out the yellow and green, or a new gas? Probably the latter!”

PARTIES AND CONCERTS
- Xenon can be found at many parties and concerts
- It is used in camera flashes and strobe lights
- Also used in many lights that take a large, instant amount of light

REACTION AND COMPOUNDS
- Since it is in the P-block it has few compounds
- Most noble gases rarely react or are involved in reactions
- It is inert and already has a full shell of electrons.

SPECTRAL LINES
OUTSIDE OUR PLANET
- Jupiter has a large amount of xenon. About 3x that of the Earth.
- Found on Mars at 0.08 parts per million
