No - not necessarily - Radon is a gas and is Atomic number 86 and a huge atom. Iodine exists as I2 and although not a gas at room tempertaure very easily becomes one and is a huge molecule.
The difference is that gases are just like air, a lot of free room, therefore the molecules move around, water/liquid is a little more condensed so molecules move less than gases, but more than solids, solids are completely compact so molecules have very little movement, but are always moving, the only thing that can make them stop moving is if the temperature reached ABSOLUTE ZERO
Gases are substances with very weak bonds between molecules.
in solids the molecules are rigid, hard to move, stuck together in liquids they are close together but can still move in gasses theyre far apart with alot of space between molecules, they can move very freely
All the elemental gases except for the noble gases come in molecules that are unstable. The noble gases are all stable, they have the maximum number of valence electrons that their outer shell can hold.
Vacuoles are the little sacs that carry out molecules.

solid. In a solid, the molecules are tightly packed together and have minimal movement compared to liquids and gases.
When molecules in liquids and gases are heated they move faster
after atoms and molecules of gases and liquids are heated, they sink?
Molecules of a gas are in permanent motion.

All gasses that are not noble gases (well xenon and heaviei forms some interesting "patterns", if not truly molecules), or plasmas, are molecular gases.
Gases are substances with very weak bonds between molecules.
The observation about gases that proved molecules can move is their compressibility. This is further corroborated by the Brownian Motion theory.

It is assumed that Ideal Gases have negligible intermolecular forces and that the molecules' actualphysical volume is negligible. Real Gases have the molecules closer together so that intermolecular forces and molecules' physical volumes are no longer negligible. High pressures and low temperatures tend to produce deviation from Ideal Gas Law and Ideal Gas behavior.
the reason there are no gases in mercury the molecules moves fast at high temperature
