Particles is a GENERAL word used in Chemistry to describe either atoms, molecules, ions or radicals, etc.

Yes, we can also say that atoms are particles. It all depends on how the questions are being phrased.

If the question state that there is a particle X that has 20 protons, 20 electrons and 20 neutrons, then this particle will be Ca atom.

But if question state that there is a particle X that has 20 protons, 18 electrons and 20 neutrons, then this particle will be Ca2+ ion.

Hope this is clear.
