Delocalized electrons also exist in the structure of solid metals. Metallic structure consists of aligned positive ions (cations) in a “sea” of delocalized electrons. This means that the electrons are free to move throughout the structure, and gives rise to properties such as conductivity.
And here’s the answer you’re looking for. A collection of related questions and answers you may need from time to time.
Where do delocalized electrons come from? – Frequently asked questions
Why do electrons become Delocalised?There have to be huge numbers of molecular orbitals, of course, because any orbital can only hold two electrons. The electrons can move freely within these molecular orbitals, and so each electron becomes detached from its parent atom. The electrons are said to be delocalized
What does it mean when electrons are delocalized?Electron delocalization (delocalization): Distribution of electron density beyond a fixed place such as a single atom, lone pair, or covalent bond via resonance or inductive effects.
Why does delocalization occur in benzene?Because the electrons are no longer held between just two carbon atoms, but are spread over the whole ring, the electrons are said to be delocalised. The six delocalised electrons go into three molecular orbitals – two in each.
Which electrons from the metal make up the delocalized electrons?Metal atoms have at least two shells of electrons, but the valence electrons are the only electrons that decouple from metal atoms in giant metallically bonded structures. The valence electrons group together, and they effectively form one giant sea of delocalized electrons.
What is the difference between localized and delocalized electrons?In general chemistry, localized electrons and delocalized electrons are terms that describe chemical structures of chemical compounds. Localized electrons are the bonding electrons in molecules while delocalized electrons are nonbonding electrons that occur as electron clouds above and below the molecule.
What kind of bond is formed by delocalized electrons?The strength of a metallic bond depends on three things: The number of electrons that become delocalized from the metal. The charge of the cation (metal).
What type of bonding involves delocalized electrons?Metallic bonding is a type of chemical bonding that arises from the electrostatic attractive force between conduction electrons (in the form of an electron cloud of delocalized electrons) and positively charged metal ions.
What kind of molecules show delocalization?One of the best known examples of a molecule in which bonding electrons are delocalized is benzene, shown below: Benzene consists of a ring of six carbons atom. The carbon atoms are all sp2 hybridized with one unhybridized p orbital.
What is another word for delocalized?displacement, transfer, Outsourcing, outposting.
Where do delocalised electrons come from in metal?The electrons from the outer shells of the metal atoms are delocalised , and are free to move through the whole structure. This sharing of delocalised electrons results in strong metallic bonding .
Where do delocalised electrons come from in metallic bond?In metals, the electrons leave the outer shells of metal atoms , forming positive metal ions and a ‘sea’ of delocalised electrons.

Delocalized Electrons Explain Benzene's Structure
- Summary: Delocalized Electrons Explain Benzene’s StructureThis diagram is often simplified by leaving out all the carbon and hydrogen atoms! In diagrams of this sort, there is a carbon atom at each corner. You have to count the bonds leaving each carbon to work out how many hydrogens there are attached to it. In this case, each carbon has three bonds leaving it. Because carbon atoms form four bonds, that…

ROCO Resonance: Delocalized
- Summary: ROCO Resonance: Delocalized Localized vs. delocalized The distinction between “localized” and “delocalized” only exists when we describe electron motion using Lewis’ bonding theory. According to this theory, localized electrons exhibit normal behavior. A localized lone pair remains close to one atom. A localized bond pair travels between two atoms. Resonance hybrids necessarily contain some “abnormal” electrons. A lone pair may seem to have some bonding characteristics; instead of…
