The larger the particle size, the slower it will diffuse. This is given by Graham's Law of effusion which states that the rate of effusion is inversely related to the square root of the molar mass of the gas.
The diffusion of a gas with a smaller molecule is faster.
You Tell me
Argon, like all of the "noble" gases, has a full electron shell.
Sodium, magnesium etc...
In strict logical inference, nothing, because there could be very dense nonmetals to compensate for the gases. However, in fact the densities of nonmetals on average are less than the densities of metals.
As you probably learned in high school, the atoms inside solids and liquids are much closer than those inside gases. The gaseous atoms are so far apart that it is beyond the abilities of our eyesight to see it, as we must rely on our smell and nerves to tell anything like that.

You will have to tell us what the particle is, but if it is an alpha particle, there are two neutrons in it.
Its temperature, its mass, and its luminosity. Its size, nor distance have nothing to do with the colour of a star, bar maybe diffusion through additional materials when viewed from Earth.
The size of a rock or rock particle is a general indicator of the distance it has travelled from the point of origin of the parent rock formation.
you can smell it
you tell me
diffusion shows that africans have moved extensively around the continent
Ozone readings of a location tell you about the CFC gases released at that place. Because CFC gases cause depletion of the ozone layer.
i don't know u tell me
The number of that type particle involved in the reaction.
Temperature is related to the average energy per particle.
They were used to tell of the presence of odorless gases in mines
