WANTED: HELIUM THE SUSPECT
We Are Coming For You Helios!
*Helium is used for:
- The Sun
- compressed air tanks
- rocket fuel
These are all the things that helium is made of or used for. Helium is very important because if we didn't have helium, we wouldn't have all the things made of helium today.
chemical symbol: "He"
- Helium hands
Color: no particular color or smell
Atomic mass: 4.00
Atomic #: 2
Metal or Non-metal: non-metal (gases are not metals because they are not solids)
Room Temperature Reaction: room temperature doesn't react with helium... just stays the same
Bohr Diagram for Helium
# of protons: 2
# of nuetrons: 2
# of electrons: 2
First "Arresting" Officer
Picture of Helium is made of

First "Arresting" Officer
- full name: Pierre Jules Cesar Janssen (also called Jules Janssen)
- born on February 22, 1824 in Paris France, died on December 23, 1907
- graduated from University of Paris in 1852 studying mathematics and physics
- later became a professor to teach physics in the University of Paris
- worked as a bank clerk for most of his life
- discovered how to observe solar prominences
- in 1873, he invented the photographic revolver (a device designed to take 180 images at the rate of one frame per second)
- in Guntar, India, on August 18, 1868 he observed that the spectral lines in the solar prominences were too bright that can be easily seen in the daylight
- in 1893, he proved that strong oxygen lines appearing in the solar spectrum was caused my oxygen in the Earth's atmosphere
Report of first "arrest"
- Officer Janssen noticed a yellow line in the sun's spectrum while studying the eclipse on August 18, 1868.
- He camped outside in Guntoor, India to watch and wait for the moon to in front of the sun and notice the solar prominences.
- During this test, Janssen discovered helium in the a total solar eclipse.
- Helium was last seen with his noble gas friends in a rocket ship and in a hot air balloon having fun on a Friday night.
- He was last seen with hydrogen, neon, argon, carbon dioxide, and oxygen.
- Helium is in the noble gas family/group where the gases are.
- The noble gases section is on the far upper right section in the periodic table.
- Helium is found everywhere in the world, everywhere you travel or go there is helium.
*Other elements that form mixtures/compounds with helium:
- Carbon dioxide
Helium is a non-reactive element, which means it doesn't react a lot to other elements. Therefore, helium barely reacts with anything.
Helium can be dangerous only if you use it carefully in a gentle way.
It is called a insert gas because it is less reactive to other elements.
This element, Helium is generally stable.
If you inhale too much Helium, you can suffocate and eventually die!
