Nitrogen is a gas at room temperature. It exists as a diatomic molecule, meaning it consists of two nitrogen atoms bonded together (N2). This gaseous state is due to the relatively weak intermolecular forces between nitrogen molecules, which allow them to move freely and fill the space available to them.
At room temperature, which is typically around 20-25°C (68-77°F), nitrogen remains in its gaseous form. It is colorless, odorless, and tasteless, making it a major component of the Earth’s atmosphere, where it makes up about 78% of the air we breathe.
Nitrogen’s state of matter can change under different conditions. For example, at very low temperatures, it can be liquefied, and at even lower temperatures, it can solidify. However, under normal room temperature and pressure conditions, nitrogen is always found as a gas.
