Question

Why are molecules like oxygen gas, O2, and nitrogen gas, N2, not greenhouse gases?(1 point)
Responses

Oxygen and nitrogen are tightly bound and cannot vibrate in a way to absorb energy.

The correct response is:

**Oxygen and nitrogen are tightly bound and cannot vibrate in a way to absorb energy.**

Both oxygen (O2) and nitrogen (N2) are diatomic molecules with symmetrical structures. This symmetry means they do not have the types of vibrational modes that can effectively interact with infrared radiation, which is essential for absorbing and re-emitting energy as a greenhouse gas does.
