Delocalized electron - Wikipedia
In chemistry, delocalized electrons are electrons in a molecule, ion or solid metal that are not associated with a single atom or a covalent bond. The term delocalization is general and can have slightly different meanings in different fields. In organic chemistry, this refers to resonance in conjugated systems and aromatic compounds. In
Explain why NaCl does not conduct electricity when …
[b]Explain why NaCl does not conduct electricity when solid but does conduct when molten or in solution[/b] NaCl (common salt) is solid in state and solid ions or compounds don''t conduct electricity. It needs to be either melted, molten or dissolved in a solution (i.e. water) first.

Graphite is a Good Conductor of Electricity
Graphite. Graphite is an important allotropic form of carbon. It is a good conductor of electricity. It is used extensively for making core of electrochemical cells (Dry Cell) and Lead pencil. Graphite has a 3 D network structure. It consists of only carbon atoms. In
Differences Between Graphene and Graphite
It conducts heat and electricity and retains the highest natural strength and stiffness even in temperatures exceeding 3600 C. This material is self-lubriing and is also resistant to chemicals. Although there are different forms of carbon, graphite is highly stable under standard conditions.
