"Particle' is just a label or description. The 'actual' whatsit is potentially unknowable in a direct fashion to our senses.
But as a label or description, particles are useful to our scientists studying these sub micro phenomena.
Curiously, electrons are really, really, REALLY tiny. Or so they seem. IIRC, even now, we don't have good scientifical numbers on just how tiny they might be. Even 'mathematical' points of zero volume (!) are possible. How can something exist without a fundamental, basic size how ever small?

I raised this question on a science board some years ago, and though I don't recall the answer, I do recall at the time being impressed that someone else with way more smarts than me had thought about it:
Do we know for a certainty that all electrons everywhere, whatever they basically may be, regardless of their size or lack thereof, are all each and everyone one of them absolutely totally identical to each other ?
Turns out they are, it's a pity I don't recall why . . .

The granting of a pardon is an imputation of guilt, and the acceptance a confession of it.
