For you to smell something it has to get to your nose be it gas, liquid droplets or dust, which dissolve in our noses or transmit their smell on some other way eg. methane is a gas and we can smell it, lemon juice is a liquid which we can smell, and powderd sulphur is a solid which we can also smell.
Odors are made by the circulation of tiny particles with this particular smell. the fact that the particles are spread out within the air and are not bonded together in a liquid or a gas suggests that yes an odor is a gas, of what would vary depending on the smell.
e.g. (I know its crude but still) a fart, methane gas is what we smell, tiny molecules of methane circulating in the air.
Argon is an inert gas that is colorless, odorless, and tasteless. As a result, argon does not have a distinctive odor.
The gas molecules travel quickly and spread out in the air, carrying the odor with them. The human sense of smell is sensitive to even small amounts of certain compounds, allowing the odor to be detected across the room. Additionally, the odor molecules stimulate sensory receptors in the nose, signaling to the brain that a gas with an odor is present.
Chlorine gas is actually yellow-green in color and has a distinct, pungent odor similar to bleach. It is not odorless.
Polysulfide rubber contains sulfur compounds that can release hydrogen sulfide gas, which has a strong and unpleasant odor. This odor is more noticeable in uncured or partially cured polysulfide rubber where the sulfur compounds are still reacting and producing gas.
Chlorine gas has a choking odor that can irritate the respiratory system when inhaled. It is commonly used in household cleaning products and in water treatment but can be toxic in high concentrations.
Hydrogen sulfide is a gas that is associated with a garlic-like odor. It is commonly found in natural gas, crude petroleum, and volcanic gases.
A few of them. Chlorine is one.
Helium is an odorless gas.
Argon is an inert gas that is colorless, odorless, and tasteless. As a result, argon does not have a distinctive odor.
This gas is radon.
A gas leak.

No! The rotten egg odor you smell is probably sulfur gas.
Iodine gas has a pungent, acrid odor similar to chlorine. It can also have a slightly sweet metallic smell.
Chlorine gas is actually yellow-green in color and has a distinct, pungent odor similar to bleach. It is not odorless.
Pure hydrogen is an odorless, colorless, and tasteless gas. It does not have a discernible odor.
If you detect the odor of gas in the boiler room, evacuate the area immediately, shut off the gas supply to the boiler if possible, and contact the gas company or emergency services. Avoid creating any sparks or flames that could ignite the gas.
