Ive been studying Maxwell equations at school and I solved several excercises regarding electrostatic fields, however, I still have some very basic unanswered questions:

When a non conductive object is charged with negative charge and a second non conductive object with positive charge approaches, there will be a discharge or transference of charge from one object to another, Is that discharge actual electrons going from one object to the other? or is it only "charge" as in energy flowing from one to the other?

To further clarify my question: imagine a lightning striking the ground, is the electric arc ( the lightning itself) a bunch of electrons going from the clouds to the ground?

    \$\begingroup\$ There is a tag called "electromagnetism" which in my opinion allows these question without having to go to physics.SE, it says and I quote: "The kind of magic without which all of this wouldn't be possible. This tag should be used for questions about the physics of the fields that charged particles create and how these fields interact. It should not be used for all questions involving electromagnetism, that would be everything " \$\endgroup\$ – S.s. Jul 19 '13 at 20:02

It is electrons that flow from one object to the other and electrons have a charge of 1.602e-19 coulombs so you can say the answer is both. Also don't interpret charge flowing as energy flowing - the two don't numerically equate.

To further clarify my question: imagine a lightning striking the ground, is the electric arc ( the lightning itself) a bunch of electrons going from the clouds to the ground?

The electric arc is current flow which of course is flow of charge
