When you rub the balloon on your hair, the balloon
will "stick" to the vertical plastic board. The
question is: where are electrons - inside
the ballon or on its surface. Thanks.

The balloon *uncharged* has as many electrons as protons. And this is a very large number. So you want to know where the *excess* electrons are located.

With static charge (electrons stored in a place) on a non-conductor (like a rubber balloon), they will be "located" where the friction was applied that removed them from your hair. Over time, they will drift across the surface (pushed by the other electrons) and out into the air. When they are present on the surface, they will try and "squeeze" other electrons in the rubber, and some of those electrons will tend to accumulate opposite the excess electrons... on the inside of the balloon.

Electrons don't like each other very much, even though they go hunting together sometimes. Like when they make a spark or lightning.

Now think about your hair. It must make do with fewer electrons. How do you think a strand of hair handles having a very few of its electrons removed? What happens to the electrons that are still left in the hair?

Still telling the old discredited claim about friction doing work to move the electrons. The issue was settled over 80 years ago. The transfer of electrons by rubbing is caused by sufficiently intimate contact to allow contact potential differences between dissimilar materials to cause electrons to transfer from less electronegative matter to more electronegative matter. Sufficiently quick separation prevents too much migration back toward the initial condition and we have charging by contact not friction!
