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 • 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.
