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.
The unreactive gas that makes up most of the air is nitrogen, which constitutes about 78% of the Earth's atmosphere. Nitrogen is a diatomic molecule (N₂) and is largely inert, meaning it does not readily react with other substances under normal conditions. This stability plays a crucial role in maintaining the balance of the atmosphere and supporting life.
The element that is an unreactive gas and sinks in the air is radon. Radon is a noble gas, which means it has a full valence shell and is largely inert, making it unreactive with other elements. Being heavier than air, it tends to accumulate in low-lying areas. Radon is also radioactive and can pose health risks when inhaled in significant quantities.
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 (N₂). This inertness makes it essential in various applications, including the production of fertilizers and in creating an inert atmosphere for chemical reactions.
A noble gas, such as helium or neon, is unreactive and has a full outer electron shell on the periodic table. This full outer shell makes them stable and less likely to form chemical bonds with other elements.
Argon (Ar) has 18 electrons. It is a noble gas with a full outer electron shell, which makes it stable and unreactive.
An example of an unreactive gas that sinks in air is carbon dioxide (CO2). Due to its higher density compared to air, it displaces air and sinks towards the ground. This property makes it useful for extinguishing fires in some fire suppression systems.

Helium. Hydrogen works too but it tends to blow up. Helium is an inert gas that is very unreactive so it makes the best option.
Nitrogen.
Nitrogen gas makes up about 78% of Earth's atmosphere.
Oxygen gas makes up just over 20% of the air around us.
Nitrogen is the gas that makes up about 78% of the Earth's atmosphere.
Oxygen is the gas that accounts for about 20 percent of Earth's atmosphere.
