Why don't electrons leave a negatively charged metal in air?

It's not a copy I have here, it's what it says more or less.

You should justify your statements, like we all do.

Proof is more important than authority. Otherwise we'd still be in Newton's era. Or should I say the middle ages.

Will you apologise for ignoring the "negatively charged" in the title, because you forgot about the following?

.. and how is this relevant to the standard lightning rod? Do you see a belt attached to a lightning rod that supplies charges to the the rod the SAME way as the van de graaf dome? Again, you are mistaking two different phenomena as being the same!

And don't tell me that you actually pay this close attention to such pictures! Really now! If you are ever at Argonne during its open house, try and come visit our Van de Graaf facility. It's WAY bigger than that, and it can accelerate electrons up to 3 MeV!

I did! I cited to papers in peer-review publications! I don't think you know what that means, though. You cited something off some "high school text". Which do you think has more of a validity in terms of completeness and accuracy? You also seem to forget that I do experiments in this area of study. I don't just read it.

I see this thread as going nowhere, considering your inability to comprehend what I have mentioned, and your refusal to even learn what has been said. So it is done.

Edit: If someone has the author and publisher of this "textbook" that has that silly quote, please PM me with the info. The least I can do is to stop this faulty info from being perpetuated.
