What are mobile charged particles?

Answer 1

I'm not too educated on this, in fact I'm still in school and learning chemistry, but from my understanding, mobile charged particles are just those that aren't bound to a single atom, and so they are known as delocalised particles (in particular, delocalised electrons freely flow inbetween cations - communal property if you will). To give you some context, if we were to inspect a lump of metal, say copper, we would see many fixed postive ions surrounded by delocalised electrons. And of course you'd know that the metals which have mobile charged particles are those that are conductors of electricity, purely because the electrons can flow easily in copper.

Answer 2

Mobile charged particles are atoms or molecules that have gained or lost electrons, resulting in a net positive or negative charge. These particles, known as ions, can move freely within a material or solution in response to an electric field. Examples include cations (positively charged ions) and anions (negatively charged ions).
