The Nobel Gases

Rachel, Danielle, Romi, and Brooke presents....

HELIUM, NEON, ARGON, KRYPTON, XENON, AND RADON IN YOUR EVERYDAY LIFE!

He(Helium)- Used in such things as neon signs and ballons. All Nobel Gasses burn at all different colors for example argon burns the color blue, helium burns a bright orange-red color. It is also used in cryogenics, and also in deep-sea breathing systems. Scientists use helium in helium tests- which can help see the age of different things that has died, but only if it has helium inside of them.


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.

History of Elements of the Nobel Gases

Element name: Krypton

Discovered:

-when: May 30, 1898

-whom: Sir William Ramsay- scottish chemist, Morris M. Travers-english chemist

-how: studying liquefied air

-where: on earth in a lab

extra: comes from the greek word ‘Kryptos’


Elements Name: Xenon
Discovered:

-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 air

EXTRA NOTES: neon is the earth’s fourth most abundant element.

Argon was discovered by William Ramsy and John Willam Strutt



Elements name: Radon

Discovered:

-when:1900

-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 electronegativities

  • low boiling point

  • gas at room temperature

Site: chemistry.about.com/od/elementgroups/a/noblegases.html


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.

  • Helium, neon, and argon if in liquid form can cause frostbite on contact.
