The delocalised electrons are free to move throughout the plane.

Delocalised electrons are thus free to move through the layers.

Graphite conducts heat and electricity due to delocalised electrons between the layers.

Polycrystalline materials are good conductors due to their regular patterns and delocalised electrons.

For example, the delocalised electrons can be moved onto the same plane by applied strains within the crystal lattice.

They have metallic bonding, in which positive metal ions are attracted to delocalised electrons.

This is because metal atoms are held together by the electromagnetic attraction from the positive ions to the delocalised electrons.

The nature of the benzene ring and its delocalised electrons prevents this sort of reaction from occurring.

More advanced models of metal properties consider the effect of the positive ions cores on the delocalised electrons.

The lone pair of oxygen electrons are considered to interact with, and form part of, the delocalised electron system of the benzene ring.

The metallic bonds then become weaker as delocalised electrons become more thinly spread as metallic radius increases.

In metals, the atoms are said have positive ions occupying the lattice positions and thus leaving delocalised electrons to move freely through the lattice.

The term is the work function (sometimes denoted , or ), which gives the minimum energy required to remove a delocalised electron from the surface of the metal.

Electrical conduction carries the requirement for conjugation along the entire length of the wire as well as a small band gap between the localised and delocalised electrons.

Further, it would usually be assumed that the intense absorption bands which give rise to the green colour of chlorophyll should be defined in terms of the delocalised electron distribution of the porphyrin-like ligand.

As the atoms increase in size going down the group (because their atomic radius increases), the nuclei of the ions move further away from the delocalised electrons and hence the metallic bond becomes weaker so that the metal can more easily melt and boil, thus lowering the melting and boiling points.

The atomisation energy measures the strength of the metallic bond of an element, which falls down the group as the atoms increase in radius and thus the metallic bond must increase in length, making the delocalised electrons further away from the attraction of the nuclei of the heavier alkali metals.

The delocalized electrons are free to move throughout the plane.

Delocalized electrons also exist in the structure of solid metals.

But, chemists are slow to switch from the delocalized electrons view.

Due to the delocalized electrons between the layers, it can conduct electricity very well.

In reality, the best way to represent the nitro group is to consider it to have delocalized electrons.

A number of π delocalized electrons that is even, but not a multiple of 4.

Metallic solids are bound by a high density of shared, delocalized electrons.

Resonance (chemistry) leads to creation of delocalized electron states.

Pyrrolidine derivatives are viewed as having a nitrogen with a partially delocalized electron pair.

Although covalent bonding entails sharing of electrons, it is not necessarily delocalized electron.

Further erasing the label of antiaromaticity is the argument that the molecule does not even have delocalized electrons.

These fluorophores fluoresce thanks to delocalized electrons which can jump a band and stabilize the energy absorbed.

The presence of such bands allows electrons in metals to behave as if they were free or delocalized electrons.

Metals make relatively good conductors of heat, primarily because the delocalized electrons are free to transport thermal energy between atoms.

In chemistry, a conjugated system is a system of connected p-orbitals with delocalized electrons.

Carbon nanotubes are metallic or semiconducting, based upon delocalized electrons occupying a 1-D density of states.

This property can be found in quantum dots, certain lanthanides and certain organic molecules with delocalized electrons.

Molecules which have a conjugated system have special properties created by the greater sharing of the delocalized electrons among many atoms.

The delocalized electrons allow metal atoms to slide past one another without being subjected to strong repulsive forces that would cause other materials to shatter.

The conventional understanding of pi stacking involves quadropole interactions between delocalized electrons in p-orbitals.

Metallic structure consists of aligned positive ions (cations) in a "sea" of delocalized electrons.

In organic chemistry, a 1,3-dipolar compound or 1,3-dipole is a dipolar compound with delocalized electrons and a separation of charge over three atoms.

The eight-membered ring is flat with equivalent bond lengths between any two types of atoms, indicative of a delocalized electron distribution.

A molecule or ion with such delocalized electrons is represented by several contributing structures (also called resonance structures or canonical forms).

Landau diamagnetism, however, should be contrasted with Pauli paramagnetism, an effect associated with the polarization of delocalized electrons' spins.
