Are all objects electrically charged?

All objects are matter, which is composed of atoms.  Every atom has the potential to change is electronic composition by adding or subtracting electrons, which induce a negative or positive charge.  As atoms congregate to become the objects we are familiar with in the macro world, they still carry their particular charges, but the effect of any given atom is reduced by the sheer numbers around it.  In other words, the positive and negative electrical charges on any given object in the macro world balance.   However, this balance can be upset, usually by the addition of electrons.  Getting shocked when touching a metal object, for example, is explained by the slightly more electrons upon your body (for whatever reason) which are conducted away by the metal.  Before discharge, your body possesses an unbalanced electric charge.
