Nitrogen, Oxygen, Flourine, Helium, Neon, Argon, Krypton, Xenon, Radon and Chlorine.
11 elements exist as gas in ordinary conditions
Chemical elements may be solid, gas or liquid.
Hydrogen, nitrogen, oxygen, fluorine, chlorine, and all the noble gases exist as a gas at standard temperature and pressure.
All group 18 elements (the noble gases) exist as monatormic gases at room temperature and standard pressure. All other elements form diatomic gases, if they exist as gas under the specified conditions. Among the listed elements there is only one noble gas: Argon
No, gases are not the only elements. Elements can exist in different states of matter, including solid, liquid, and gas. There are 118 known elements on the periodic table, each with its own unique properties.
All elements and compounds can exist as a gas if heated sufficiently.

Chemical elements may be solid, gas or liquid.
Atoms of all elements exist in the state of matter known as the gas phase.
The chemical substances found in the atmosphere exist as gases.
Hydrogen, nitrogen, oxygen, fluorine, chlorine, and all the noble gases exist as a gas at standard temperature and pressure.
Fluorine gas is one of the most reactive elements that exist and it will react with most metals.
That is not true. Every element takes the form of a gas if it is sufficiently heated. In other words, all elements have some boiling point. For some elements the boiling point is very high, but it does exist.
88 different elements exist in nature.
No, krypton is a noble gas and does not exist in allotropes like some other elements. It is a colorless, odorless gas that is typically inert and does not readily form compounds with other elements.
