Nitrogen.
Earth
Hydrogen gas is used to make margarine, through a process called hydrogenation. As for fertilizers, ammonia gas is commonly used as a key component due to its high nitrogen content, an essential nutrient for plant growth.
in the plumbing world nitrogen is used for purging the air, O2, out of medical gas lines or refrigeration lines for air conditioners. nitrogen is used because it does not burn like O2 thus leaving the inside of the pipe clean.
Argon is the unreactive gas that makes up 1 percent of the Earth's atmosphere. It is a noble gas and is commonly used in applications where an inert atmosphere is required, such as in light bulbs and welding.

Copper is unreactive and will not react with acids to liberate hydrogen gas. However it may react if concentrated and oxidising acids are used.
Helium
No. Neon is a noble gas and is unreactive.
The element you are referring to is neon. Neon is a noble gas known for being colorless, odorless, and extremely unreactive. It is commonly used in electric lights and neon signs due to its ability to produce a bright red-orange glow when electrified.
Helium is considered the most unreactive gas because it is a noble gas with a full outer electron shell, making it very stable and unlikely to react with other elements.
An unreactive element found in air is nitrogen. Comprising about 78% of Earth's atmosphere, nitrogen is a colorless, odorless gas that does not readily react with other elements due to its stable diatomic molecule (Nā). This inertness makes it essential in various applications, including the production of fertilizers and in creating an inert atmosphere for chemical reactions.
nitrogenThe Haber process converts nitrogen gas into nitrogen fertilizers that help plants grow.
