He said that the loaded one isn't. I'm in 8th grade at high school, so it's possible that something like that exists, but it's not…

I cannot say whether this is true in quantum mechanical terms.
The question is when exactly can one speak of a quasi-part in this scenario?
And I don’t know exactly about it. But excited By your question, I put it on my list and will inform me on occasion.
Thank you for your suggestion!
What do you mean with hole? An atomic shell is nothing material.
With hole I mean a virtual positive charge within a De-Broglie wave
Oh, okay. I guess your assumption is true. However, I do not know myself well enough thematically when you should trust my feeling.
