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

5
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

6
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. Theres a lot to know and its very
  interesting so I recommend learning about it.
