Electrons come from atoms
In summary, atoms have electrons. When they give them away,
atoms become ions. Ions are charged.

<font face="verdana, arial, sans-serif" size="4">Everything is made of
atoms. Atoms have an equal number of electrons and protons. Protons are
trapped in the core of the atom, called the nucleus. Electrons, outside
the nucleus, can be removed. It does not require much energy to do this.
Sometimes rubbing two materials together will remove electrons. <b>An atom
that either gained or lost an electron is called an ion.</b></font>
