Question

Co2 is generally heavier than oxygen and nitrogen why does it form lower layer in the atmosphere

Answer 1

It forms on the lower level because Co2 is constantly being made from cars and planes so it will sink to the bottom of the atmosphere

Answer 2

Hey mate here is your answer..................!!☺➡⬇⬅.

:-) Here I am giving two reasons, one is simply based on theory and other is based of numericals..............!!:-)

➡ THEORY BASED.
________________⬇

There are number of reasons that CO2 does NOT form a lower layer. they include 

1) CO2 is in the ppm range. 300 molecules CO2 / 1,000,000 molecules air. Very dilute... brownian motion effects would prevent this seperation 
2) diffusion effects. 
3) our atmosphere is constantly in motion and constantly mixing. due to pressure differences cause by temperature changes. 
4) the are many structures on our planet also cause air to mix. mountains for example.

:-) NUMERICALLY.
_______________☺⬇

PV = nRT 
n = mass / mw 

PV = (mass / mw) RT 
mass / V = density = mw x P / (RT) 

the higher the mw, the higher the density at the same T and P... 
mw CO2 = 44 
mw O2 = 32 
mw N2 = 28 
therefore.. CO2 is DENSER than O2 and N2 .
