WHAT IS ARGON?
By Matthew Prell
WHAT ARE ELEMENTS?
Definition: A element is a substance in which all the atoms in it are the same kind
I will be presenting the structure, history, and importance of Argon.

WHAT IS THE STRUCTURE OF ARGON?
a light noble gas that can glow purple and blue under an electricle charge
18 protons, 18 electrons, 22 neutrons
Atomic weight: 39.9 40
Atomic number: 18
Symbol: Ar
WHAT IS THE HISTORY OF ARGON?
Discovered by Sir William Ramsay and Lord Rayleigh in 1894
Argon was discovered by taking away air and was left with a substance stronger the nitrogen
WHY IS ARGON IMPORTANT?
Uses: inert shielding gas in high temputrue industrial process and in most electric light bulbs
Uses in past: nothing Uses in future: I predict that Argon will be used fully in blue
or purple light bulbs because it glows purple and blue under an electrical charge
INTERESTING FACTS
o Argon was the first noble gas so it started the noble gas column
o Atomic radius: 174 Pmo Melting point: -189.35 degrees Celsius o Boiling point: -185.85 dredgers Celsiuso Argon is radioactive
CONCLUSION
I learned all about argon, well not all, but a lot. I learned its uses, origin, meaning, and much more. I learned that hydrogen, argon, and fluorine (HArF) at -265 digrees Celsius makes argon fluorohydride. Also that argon glows blue and purple. There’s a lot to know and its very interesting so I recommend learning about it.
