Does the movement of electrons to atoms or from atoms make ions?
What types of ions are formed when atoms gain or lose electrons?
Difference between metallic and electrolytic conduction?
Metallic conductance involves the movement of electrons throughout a metal. There are many metal atoms in a sheet of metal such as copper. The outer electrons of these atoms become delocalized (not fixed in one place). They are therefore able to move about the metallic sheet and so conduct electricity. Electrolytic conduction involves the movement of ions (charged species formed when an atom loses or gains electrons) throughout a pure liquid (for example molten NaCl) or solution such as NaCl and water. Main difference - one invloves the movement of electrons and the other involves the movement of ions.
