Atoms and Electrons

Atoms are the smallest particles of a chemical element that can exist having parts called the nucleus and outer shells or orbit. The nucleus contains neutrons which have no charge and are neutral and protons a positive charge. On the outer shells, there are electrons, which produce a negative charge. These electrons can be gained, lost or shared, depending on how many are left on the last shell.
