The principal oxides of Group VII Elements are Ferrous Oxide, Ferric Oxide, Ferro-Ferric Oxide. The oxides of nitrogen are formed during high temperature combustion, are present in exhaust gases from these processes and are responsible for the degradation of the quality of air. The principal oxides of nitrogen, NOx, are Nitrous Oxide, Nitric Oxide, Nitrogen Dioxide, Nitrogen Pentoxide, and Dinitrogen Tetroxide. The lower oxides of nitrogen are neutral oxides. The higher oxides of nitrogen are acidic oxides.
All oxides of nitrogen are polar covalent compounds.
Oxidising Agent An oxidising agent is a substance which oxidises another substance. Ozone Ozone, O3, is the triatomic isomer of oxygen, O2, and it is a powerful oxidising agent. The presence of ozone in the stratosphere is responsible for the absorption of ultra-violet wavelengths from the sunlight. All Rights Reserved.
