The Nobel Gases
Rachel, Danielle, Romi, and Brooke presents....
HELIUM, NEON, ARGON, KRYPTON, XENON, AND RADON IN YOUR EVERYDAY LIFE!
Ne(Neon)- Neon is inside: neon lights, fog lights, TV kinescopes, lasers, voltage detectors, luminous warnings, and advertising signs.
Ar(Argon)- Argon is i things such as, electronics, lighting,glass, metal fabrications.
Kr(Krypton)- Like Argon, Krypton can be found in energy efficient windows, fuel sources, lasers, and headlights.
Xe(Xenon)- Xeon is in candescent lighting, development in x-rays, plasma display panels and much more.
Rn(Radon)- It is said to be the second most frequent cause of lung cancer next to cigarette smoke. But the plus side to Radon is that it can used in: radiotherapy- used to implantable seeds made of glass or gold primarily used to treat cancer, also relief from arthritis and bathing.
up and personal with the members of the Noble Gas family!
History of Elements of the Nobel Gases
Element name: Krypton
-when: May 30, 1898
-whom: Sir William Ramsay- scottish chemist, Morris M. Travers-english chemist
-how: studying liquefied air
-where: on earth in a labextra: comes from the greek word ‘Kryptos’
Elements Name: Xenon
-when: July 12, 1898
-whom: Sir William Ramsay- Scottish chemist, Morris M. Travers- english chemist
-how: study of liquefied air-where: in a science lab on earth
He- helium,Whats in the name- for a greek god of sun: helious. Its the second most abundant element in the universe.
BY WHOM- Pierre-Jules-Cesar Janssen, a french astronomer.
HOW: Noticed a yellow line on the sun’s spectrum when studying a total solar eclipse
WHERE: first discovered on the sun before it was found on earth.
WHEN: 1868 was found on the sun hunt to find Helium on earth ending on 1895
Ne- WHEN: Shortly after the discovery of the element Krypton in 1898
BY WHOM: Sir William Ramsay, a scottish chemist and Morris M. Travers, an english chemist
HOW: through a study of liquefied air
WHERE: through the study of liquefied airEXTRA NOTES: neon is the earth’s fourth most abundant element.
Argon was discovered by William Ramsy and John Willam Strutt
Elements name: Radon
-whom: Friedrich Ernst Dorn, a German chemist
-how: studying radium's decay chain-where:germany
All about the periodic table and the elements in it
3 Details Uses of the Noble Gases;
used for the filament in light bulbs
used in glow sticks/neon lights
used in welding and space technology
2. Information section: (q #1,3)-
1) Describe the meaning behind the position on the periodic table
Extra info: known as inert gases
very non-reactive because of its full valence shell
tendency to gain/ lose electrons
high ionization energies
low boiling point
gas at room temperature
3) What does this group react with?
reacts with extremely reactive elements with correct amount of activation energy produces chemical compounds
reacts with the element Fluorine,along with others in the same period.
- Example: Xenon reacts with Fluorine
If a lot of a noble gas is released into the air, then it can cause suffocation. If you breath great amounts of them you can get dizzy, vomit, pass out, or even die.http://www.lenntech.com/periodic/elements/ne.htm
- Helium, neon, and argon if in liquid form can cause frostbite on contact.
