Molecular models of the various oxides of nitrogen, most of which are atmospheric pollutants given out by car exhausts, power stations, etc. The blue spheres represent nitrogen atoms & the red spheres oxygen atoms. The six oxides depicted are: nitrogen monoxide (NO), nitrogen dioxide (NO2), dinitrogen oxide (nitrous oxide, N2O), dinitrogen trioxide (N2O3), dinitrogen tetroxide (N2O4) and dinitrogen pentoxide (N2O5).
