SUMMARY

Ozone (O3) plays a crucial role in atmospheric chemistry, primarily formed through the photodissociation of diatomic oxygen (O2) when exposed to ultraviolet radiation. The process involves the breaking of the O2 covalent bond, resulting in reactive oxygen atoms that subsequently bond with O2 to create O3. Contrary to some claims, O2 is not a greenhouse gas, while carbon dioxide (CO2) and chlorofluorocarbons (CFCs) are significant contributors to atmospheric warming. The discussion clarifies misconceptions about the formation and reactivity of ozone and the timeline for CO2 and CFCs entering the atmosphere, which is approximately 40 years.

PREREQUISITES
  • Understanding of atmospheric chemistry concepts
  • Knowledge of photodissociation processes
  • Familiarity with greenhouse gases and their effects
  • Basic principles of molecular bonding and reactivity
NEXT STEPS
  • Research the process of photodissociation in atmospheric chemistry
  • Study the role of ozone in the stratosphere and its environmental impact
  • Explore the differences between greenhouse gases, specifically CO2 and CFCs
  • Investigate the timeline and mechanisms of atmospheric gas interactions
USEFUL FOR

Environmental scientists, atmospheric chemists, educators, and anyone interested in the dynamics of atmospheric gases and their impact on climate change.

Is this statement right?

Let me explain a few things about the chemistry of the atmosphere.There are two types of oxygen up there.O2 and 03.O2 is the result of CO2 bonding with 03.02 is what keeps the Earth warm.and it takes 40 YEARS for CO2 and other cfcs to make its way up into the atmosphere

Uh. Correct me if I'm wrong, but...
Atmospheric O2
Photodissociation breaks up the O2 and then the O and O2 then form O3, no?
 
Beats me, someoen correct you if your wrong ;)

Correct...
O2 is the result of CO2 bonding with 03.
No. Most O2 is generated from photosynthesis.
02 is what keeps the Earth warm.
AFAIK, O2 is not a greenhouse gas. CO2 is, though, as are CFCs.
...and it takes 40 YEARS for CO2 and other cfcs to make its way up into the atmosphere
CO2 is not a CFC - as the name implies, ChloroFluoroCarbons contain chlorine, fluorine, and carbon.

The 40 years number sounds vaguely familiar, but I'm not sure about the context.
 
yep.

O3 is made when ultraviolet radiation with enough energy in each photon to break the dual O2 covalent bond hits a molecule of O2. That molecule breaks into two separate O1 atoms, which are extraordinarily reactive, as soon as an O1 atom hits another O2 molecule it forms a third bond with the O2 molecule, making an O3 ozone molecule. Ozone has a very short life time if there is any material that can combine with oxygen in the area (bacteria, metals, practically anything organic at all). It will, on contact, liberate an oxygen atom, turning back into O2, and burning whatever it touched.
