Discovered by Sir William Ramsay and Morris M. Trevars in 1898
Discovered the element through an experiment involving liquefied
air
 Sir William Ramsay and Morris M. Trevars are also credited to be
the founders of Krypton in 1898


 Invented the Geissler tube in 1855
 Were used with electrical generators to
conduct experiments
 These tubes enabled gasses to glow (would
use low pressure and voltage from the
electrical generators)

Developed the first neon signs
Claude patented the first neon lighting tube
in 1915
First showed his work in Paris where he
displayed two of his glass tubes
Claude is most famous for not only creating
but also selling neon-filled glass tubes in the
shapes of letters

Neon is the fourth most abundant element in
the entire universe!!
Only 0.0018% of the world’s atmosphere in
made of neon
You can see a neon sign from up to 300 or 400
feet away (another reason why neon signs are so
affective).
Neon derives from the word “neos” in Greek
“Neos” means new gas
