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.
The pressure of the fusing gasses
gravity
'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.
They are called noble gasses. He,Ne,Ar are few examples.
because they are not rapidly react with any other compounds are elements
