where are electrons found in an atom and what electrical charge and mass do they have An electron can be "bound" to the nucleus of an atom by the attractive Coulomb force.  If the number of electrons is different from the nucleus' electrical charge, such an atom is called an ion. which theory explains or is based on this? Atomic Theory, Quantum Theory what exactly is the part of the atom mentioned above, initially? The electron is a subatomic particle, whose electric charge is negative one elementary charge. who discovered that it has two charges? French chemist Charles François du Fay what is this particle mentioned above? Subatomic particles are smaller than atoms. They can be composite particles, such as the neutron and proton; or elementary particles, which according to the standard model are not made of other particles. what method is used to divide the atom? Nuclear physics

Charles François de Cisternay du Fay [SEP] Introduction
Charles François de Cisternay du Fay (14 September 1698 – 16 July 1739) was a French chemist and superintendent of the Jardin du Roi. He discovered the existence of two types of electricity and named them "vitreous" and "resinous" (later known as positive and negative charge respectively). He noted the difference between conductors and insulators, calling them 'electrics' and 'non-electrics' for their ability to produce contact electrification. He also discovered that alike-charged objects would repel each other and that unlike-charged objects attract. He also disproved certain misconceptions regarding electric charge, such as that of Dr. Stephen Gray who believed that electric properties of a body depended on its colour.
