Yes - that's the reason Earth has an atmosphere.
Argon and Helium. Being inert gasses, they do not react with anything.
Nobel gasses.
No. They do not have enough gravity to hold on to the gasses.
The Noble gasses.
The noble gasses, gold and platinum.
An atmosphere is the sphere of gasses (like oxygen)held by a planet's gravity.
gravity
The pressure of the fusing gasses
'atoms' cannot 'react' to air pressure for air pressure is generated from atoms (oxygen, noble gasses, water).
Almost anything except noble gasses, it has a valance of 4, the same as carbon.
because they are not rapidly react with any other compounds are elements
