simple and easy a comet a comet has a solid center nucleus that contains rock particles trapped in frozen liqud
this forms the tail: as it moves closer to the sun the "outer ice" turns to gas and the solid particles (pieces) turn to dust
gases
Democritus
these particles are called quarks
:Whilest "space" is but a vaccuum, there are still trace amounts of gas particles in the vast emptiness of that which we call "space." Take nebulae for instance, they are but giant collections of plasma particles, which are but a combination of gas and liquid. The accretion disks around black holes are made of plasma and gas as well. So in short, yes, there are particles of gas in space.
Protons and Neutrons
A galaxy.
nebula
Normally free floating particles and gases such as oxygen, nitrogen etc.
gases because of the space between the particles
The winds of outer space are called solar winds. Not really air but it is the movement of gases and charged particles coming from the sun or the planets into outer space.
cause the particles have alot of space
It is called compressibility. The compressibility of gases can be explained by the kinetic particle theory: due to the large amount of space between the gas particles and the weak attraction forces between them, gases can easily be compressed (the particles are brought closer to each other, thus reducing the volume of the gas).

Because in space there are no particles (this is called a vacuum), however conduction and convection require particles to work eg. solids, liquids and gases have particle arrangements. So thermal radiation has to travel through space via radiation as space is a vacuum and particle-less.
