Verified step by step guidance

Understand the concept of greenhouse gases: Greenhouse gases are components of the atmosphere that can absorb and emit infrared radiation, leading to the greenhouse effect, which warms the Earth's surface.

Identify common greenhouse gases: The most well-known greenhouse gases include carbon dioxide (CO2), water vapor (H2O), methane (CH4), nitrous oxide (N2O), and ozone (O3).

Analyze the given options: Review each option to determine if it is a known greenhouse gas. Carbon dioxide (CO2), water vapor (H2O), and methane (CH4) are all recognized as greenhouse gases.

Consider the properties of nitrogen (N2): Nitrogen makes up a significant portion of the Earth's atmosphere but does not absorb infrared radiation effectively, thus it is not considered a greenhouse gas.

Conclude which is not a greenhouse gas: Based on the analysis, nitrogen (N2) does not contribute to the greenhouse effect and is therefore not a greenhouse gas.
