Quick Answer. The net electric charge of the nucleus of an atom is positive due to the presence of charge-carrying particles known as protons. The outer shell of the atom is negatively charged as a result of carrying electrons in a diffuse cloud. Atoms always have a net neutral electric charge.
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 ...
