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.
