Delocalized valence electrons are electrons in a molecule or solid that are not associated with a specific atom but instead spread out over multiple atoms. They are free to move throughout the material, giving rise to properties like electrical conductivity in metals and the ability to absorb or emit light in certain organic compounds.

Which phrase best describes a metallic bond?
A metallic bond is a type of chemical bond where electrons are free to move throughout the material, creating a sea of delocalized electrons that hold the metal atoms together. This results in properties such as high electrical and thermal conductivity, malleability, and ductility.
Which electrons from the metal make up the delocalized electrons?
The valence electrons from the metal atoms are the ones that contribute to the delocalized electron cloud. These electrons are free to move throughout the metal structure, providing electrical conductivity and other important properties.
How many valence electrons are found in a krypton atom?
A krypton atom has 8 valence electrons in the 4s and 4p orbitals.
How many valence electrons does S2- have?
Sulfur (S) has 6 valence electrons. The S2- ion gains two electrons, bringing the total to 8 valence electrons.
The electrons that occupy the outermost filled shell are called?
The electrons that occupy the outermost filled shell are called valence electrons. These electrons are involved in chemical reactions and determine an element's reactivity.
Why metal are good electrical conductivity?
Delocalized valence electrons
What are free electrons or delocalized electrons?
Free electrons or delocalized electrons are electrons in a material that are not bound to a specific atom or molecule. These electrons are able to move freely throughout the material, contributing to its electrical conductivity. Delocalized electrons are commonly found in metals and conductive materials.
Which types of atoms pool their valence electrons to form a sea of electrons?
Metal atoms pool their valence electrons to form a sea of delocalized electrons in a metallic bond. This results in unique properties such as conductivity and malleability.
What happens to the valence electrons of atoms in metallic bond?
In metallic bonding, valence electrons are delocalized and free to move among the atoms. This creates a "sea of electrons" that holds the metal atoms together in a lattice structure. The sharing of electrons in this way gives metals their characteristic properties, such as conductivity and malleability.
Why is the metallic bond in aluminum stronger than metallic bond in sodium?
The metallic bond in aluminum is stronger than in sodium because aluminum has more valence electrons that can be delocalized and contribute to the bond strength. This results in a higher charge density and stronger attraction between the metal atoms and the delocalized electrons, compared to sodium which has fewer delocalized electrons due to its lower number of valence electrons.
Delocalized valence electrons are typical of ionic compounds?
Delocalized valence electrons are more typical of metallic compounds, where electrons are free to move throughout the structure. In ionic compounds, electrons are transferred from one atom to another, leading to the formation of ions with localized charges.
What happens to a valence electron in a metallic bond?
In a metallic bond, valence electrons are delocalized and are free to move throughout the entire structure of the metal. This leads to properties such as high electrical and thermal conductivity. The mobility of these electrons allows metals to conduct electricity and heat efficiently.
What do delocalised valence electrons moving between nuclei do?
Delocalised valence electrons moving between nuclei contribute to the metallic properties of a material by allowing for high electrical conductivity and thermal conductivity. These electrons are free to move throughout the structure, creating a "sea of electrons" that can carry electric current or heat energy efficiently.
Why are the valence electrons found in metallic bonds different from other bonds because of what?
their valence electrons are free-roaming they allow for the conductivity of electricity APEX :) <3 JAmie
Metallic bonds are formed from the sharing of valence electrons.?
false
How do you rank the bond types by increasing delocalization of the valence electrons of least delocalized equals 1 and most delocalized equals 4 A Ionic Metallic B Polar covalent C Pure covalent?
Ionic - least delocalized electrons due to transfer of electrons from one atom to another. Pure covalent - electrons are shared equally between atoms in a bond, leading to localized electrons. Polar covalent - electrons are shared unequally between atoms, causing partial electron delocalization. Metallic - most delocalized electrons due to delocalized electron sea that allows electrons to move freely throughout the metal lattice.
