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.

Argon’s atom - - - - - - P=18 - - - - - - N=22 - - - - - -

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 Argon was the first noble gas so it started the noble gas column Atomic radius: 174 Pm Melting point: -189.35 degrees Celsius Boiling point: -185.85 dredgers Celsius 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.
