Diagram showing field lines and equipotentials around an electron, a negatively charged particle. In an electrically neutral atom, the number of electrons is equal to the number of protons (which are positively charged), resulting in a net zero overall charge. Charge is the fundamental property of forms of matter that exhibit electrostatic attraction or repulsion in the presence of other matter.
must be something in the atom much heavier than an electron to account for the mass of the atom 4. suppose an atom has a small central core (nucleus) which contains most of the mass of the atom and carries a positive electric charge that attracts the negative electrons (helping to keep them in orbit around this nucleus) . must be some positive electric charges inside the atom to compensate for negative charges of the electrons 3. scattering must be due to encounters with charged atomic ...
