Hydrogen, nitrogen, oxygen, fluorine, chlorine, and all the noble gases exist as a gas at standard temperature and pressure.
The three elements that are not solid, liquid, or gas are bromine, mercury, and francium. Bromine is a liquid at room temperature, mercury is a liquid at room temperature, and francium is a solid due to being a metal.
most of the elements are solids at room temperature.

Fluorine is a pale yellow gas at room temperature, with a strong odor. It is highly reactive and can form compounds with most elements.
At room temperature, the state of matter for elements varies. Most metals, such as iron and copper, are solids, while mercury is a notable exception as it is a liquid. Nonmetals can be gases, like oxygen and nitrogen, or solids, like sulfur and phosphorus. Thus, elements can exist in all three states—solid, liquid, and gas—at room temperature depending on their specific properties.
Helium is a colorless, odorless, tasteless and non-toxic gas at room temperature. It exists as a monatomic noble gas and is therefore inert and unreactive. It belongs to group 0 of the Periodic Table of Elements.

Oxygen
N2 is not solid at room temperature. This is one of the diatomic elements that are in the gaseous state at room temperature.
At room temperature, oxygen is a gas.
