Title: OXYGEN


1
OXYGEN
  • Presentation and critical information
    concerning the discovery of a new element
  • Billy A., PhD
  • Fellow, American Academy of Sciences

2
Oxygen- History of Discovery
  • In the past few months, while attempting to
    synthesize gold from common dog droppings,
    curious reactions were observed

3
Eureka!
  • Process involved heating the dung to flash point
  • Fire erupted
  • Water was used to extinguish the fire

4
A common element
  • Involved hours of tedious work
  • It was discovered that an element existed common
    both to water and in combustion
  • The element was capable of accelerating the
    combustion rate
  • The element was also present in the water, bonded
    to hydrogen

5
Naming the element
  • Difficult decision
  • Who should be recognized?
  • Does the name relate to the element?
  • How easy is it to pronounce?
  • Does the name sound stupid?
  • I couldnt call it ..you know..that one gas

The New Element Is Named..

OXYGEN
8
Oxygen Pertinent information
  • Atomic Number 8
  • Electron Configuration He 2s2, 2p4
  • Atomic Mass 15.9994
  • Most common elementary substance O2O3

9
Characteristics
  • Oxygen is a colorless, odorless, and tasteless
    gas
  • -No wonder it was so difficult to discover
  • Oxygen makes up 21 of the atmosphere
  • Slightly soluble in water
  • Poor conductor of heat and electricity

10
Characteristics
  • Oxygen supports combustion but does not burn
  • It is an extremely active chemical
  • Oxygen can form compounds with almost all
    elements except inert gases
  • It unites with other elements to form oxides
    e.g. carbon monoxide

11
Characteristics
  • Oxygen is denser than air
  • It is a gas at room temperature
  • Combines with hydrogen to form water
  • Part of the polar covalent bond of water,
    useful for attracting opposite charges
  • Contains 6 electrons in its outer shell

Summary
  • Thank you for allowing this lighthearted look
    into oxygen. For more information on the history
