Argon.
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.
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.
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 two unreactive gases in the air are nitrogen (about 78%) and oxygen (about 21%).
Helium
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.
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.
Nitrogen.
No. Neon is a noble gas and is unreactive.
When liquids and gases are heated, convection currents are formed. With liquids, the heated fluid rises, cools down and then sinks back, causing a circular motion. In gases, warm air or gas rises and cooler air or gas sinks, creating vertical movements.
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.
because the gas under the ocean that sinks ships and air craft is oxygenated in the water.
