Helium
By: Hannah Ross 

Picture
Picture
  • Name: Helium 
  • Symbol: He
  • Atomic number: 2
  • Atomic mass: 4.002602 u ± 0.000002 u 

  • History/discovery: Helium was first discovered in 1868 by Pierre Janssen, a French astronomer. He was watching a solar eclipse in India when he saw yellow spectral emission lines. It was then named helium by Norman Lockyer, an English astronomer. 

  • Abundance in the universe: Helium is the second-most abundant element in the universe. It makes up 0.0005% of the earth’s atmosphere. The small amount of helium in the earth’s atmosphere is not held to the earth by gravity but, rather lost into space - in other words gravity doesn’t hold helium down.

  • Useful in every day life: The most popular use of helium is in balloons because it makes them rise. The Goodyear blimp is another popular use of helium. 

  • Is helium reactive?: It is non-reactive. Since its shell is full it doesn’t form compounds with anything. Its shell only has room for its 2 electrons. 

  • Interesting things: 
-helium can be observed at 587.49 nanometers in the spectrum of the chromosphere of the Sun
-was named after the Greek name for the sun, Helios
-helium makes people’s voices high 


Poem/literary reference: A poem called “Helium” by Siobhan Buchanan:
I am Helium 
I am number 2 
I hate Mixing with other Chemicals 
I love to be by myself at the top 
You cant see me, taste me or smell me 
I am Helium 
I can make voices sound funny, if I try! 
I can make things float for I am lighter than the sky 
I can go miles under the sea 
And still breathe! 
I am number 2 
I am Helium and its just for me and you! 


Runaway Blimp video: This week a military blimp broke lose from were it was tied down in Maryland. It floated all the way to Pennsylvania and landed there.
