Nitrogen dioxide is formed as a result of the combustion of fossil fuels, industrial processes, and certain chemical reactions. It is a highly reactive compound and plays a significant role in atmospheric chemistry and the formation of smog. Nitrogen dioxide is considered harmful to human health and the environment, and efforts are made to control its emissions and reduce its impact on air quality.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335551550&quot;:6,&quot;335551620&quot;:6,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\"> <\/span><\/p>\n<p><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\"> <\/span><\/p>\n<p><b><span data-contrast=\"auto\">Structural Formula of Nitrogen Dioxide<\/span><\/b><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\"> <\/span><\/p>\n<p><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335551550&quot;:2,&quot;335551620&quot;:2,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\"> <img loading=\"lazy\" class=\"size-full wp-image-636286 aligncenter\" src=\"https:\/\/infinitylearn.com\/surge\/wp-content\/uploads\/2023\/06\/Screenshot-2023-06-25-235737.png\" alt=\"\" width=\"262\" height=\"137\" \/><\/span><\/p>\n<p><span data-contrast=\"auto\">In this structure, the nitrogen atom (N) is connected to two oxygen atoms (O) by double bonds, and there is a lone pair of electrons on the nitrogen atom.
