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 Atomic number: 18 Symbol: Ar 40

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? ü Uses: inert shielding gas in high temputrue industrial process and in most electric light bulbs ü Uses in past: nothing ü 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 Pm o Melting point: -189. 35 degrees Celsius o Boiling point: -185. 85 dredgers Celsius o Argon is radioactive

CONCLUSION q 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 (HAr. F) 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.
