If we did not have them everything would not be here because everything is made out of particles, we would not have chemical reactions and we would not know how everything is made because we would not know bout particles.
it is important to separate and purify substances so that: 1.we can get them in their pure form. 2.to remove undesirable particles from them.
The electrons
The particles are tightly packed so they vibrate.
One important part of the particle theory for diffusion is that particles are in constant random motion. This motion allows particles to spread out and mix with other particles in a process known as diffusion.
Indistinguishable particles are particles that are so similar or identical that they can not be distinguished from another. Electrons and sometimes atoms and molecules can be indistinguishable particles.
Particles in a suspension are larger than the particles of a solution, but they are not always so small that they cannot be easily seen with the eye.
So that they can see atoms and cells and other tiny things like particles
dust cover is protect your computer from dust particles so dust cover is important i also covered my computer to dust cover

The electrons
It needs particles, so Air, Liquid or Solid to travel. so the medium is any particles, so if there is no particles, sound cannot travel.

The so-called alpha particles ARE helium nuclei.
External irradiation is not so important; inhalation or ingestion of beta rays emitters can be dangerous.
particles in a solid are packed so close together they can only
