Other dipole induction mechanisms also exist in molecular (as opposed to monatomic) gases and in mixtures of gases, when molecular gases are present.
In this narrowest sense, the only pure paramagnet is a dilute gas of monatomic hydrogen atoms.
Monatomic solids at room temperatures have approximately the same specific heat of 3k per atom, but at low temperatures they don't.
The specific heat capacities of substances comprising molecules (as distinct from monatomic gases) are not fixed constants and vary somewhat depending on temperature.
If hydrogen gas were monatomic and oxygen diatomic, the gas volume ratio would be 4:1.
In such monatomic cases, there is a clear trend in the sizes of such species, with atomic radius decreasing as charge increases.
They are all monatomic gases under standard conditions, including the elements with larger atomic masses than many normally solid elements.
For example, all noble gases are colorless, monatomic gases with very low reactivity.
