Atmosphere - composition of gases : )

Here is the amazing fact about the composition of our Earth's atmosphere. As we know the atmosphere is made up of many different gases, some of which is presence in such a minute amount that we don't even know of their presence around us! 

Lets look at the gases around us (they are ranked according to their volume in the atmosphere):

1st. Nitrogen (N2) with a percentage of  78.084%. (Although we humans have not much use, there's plenty of those fellers jumping around us.)

2nd. Oxygen (O2) with a percentage of 20.946%. (Now THIS is the guy that we depend on the most for us to be able to stay alive, and for me to be sitting in front of my comp designing this resource package.)

3rd. Argon (Ar) with a percentage of 0.934%. (So ya stop giving your pooor computer that what-the-hell-i-thought-the-third-should-be-CO2  stare and believe this, it's ARGon the noble gas!)

4th. Carbon Dioxide (CO2) with a percentage of 0.0383%. (Here comes our first compound gas, and the "bad guys" who can be seen escaping from your nostrils at this very moment, through Mrs. Chua's third eye of course.)

5th. Neon (Ne), 0.001818%. (second noble gas :)

6th. Helium (He), 0.000524%. (third :| 

7th. Methane (CH4), 0.0001745%.

8th. Krypton (Kr), 0.000114%. (fourth :(

9th. Hydrogen (H2), 0.000055%  (Joel: Hey dat's me!) (Steven: Shut up and carry on with this!)

10th. Nitrous oxide (N2O), 0.00003%

11th. Xenon (Xe), 0.000009% (fifth... Dude, start wondering why are these noble gases taking up so much spaces in our atmosphere -_-|||)

12th. Ozone (O3), 0.0% to 0.000007%. (Finally! Our dear ozone! Where have you been?!)

...

And there's others down the list like nitrogen dioxide, iodine, carbon monoxide and ammonia, not forgetting our {H2O}(g), water vapour, which varies in percentage for different areas on earth.
