What are different between conduction of electricity in solids and liquids?
Answers
Conduction in solids:
Among solids, metals are good conductors of electricity. In metals, some electrons are not very tightly bound to the atoms. They move about randomly in different directions within the metal.
Conduction in liquids:
Molten metal’s and mercury (a liquid metal) conduct electricity. The current through them is constituted by the flow of electrons. Other liquids conduct electricity because they have ions. What are ions? Under some conditions, an atom may lose one or more electrons, which get added to another atom.
The atom that loses an electron (or electrons) has more protons than electrons. So, it becomes positively charged. And the atom that gains the electrons has more electrons than protons. So, it becomes negatively charged
