The chemical formula for nitrous oxide is N2O. This compound consists of two nitrogen atoms and one oxygen atom. Nitrous oxide is recognized for its significant role as a greenhouse gas, contributing to the warming of the atmosphere due to its ability to trap heat.

In contrast, NO2 is the chemical formula for nitrogen dioxide, which is a different compound and a pollutant, rather than a greenhouse gas with the same properties as nitrous oxide. NH4 indicates the ammonium ion, which is not a gas but rather a cation commonly found in fertilizers and other compounds. CO2 refers to carbon dioxide, another well-known greenhouse gas but distinct from nitrous oxide in its chemical structure and atmospheric effects. Understanding these distinctions highlights the specific importance of N2O in discussions on greenhouse gases and climate change.
