The type of crystalline solid that has atoms surrounded by mobile valence electrons is known as a metallic solid. In these solids, the valence electrons are delocalized and can move freely throughout the structure, contributing to properties such as electrical conductivity and malleability. This electron sea model explains the characteristic behaviors of metals, including their ability to conduct heat and electricity.

Conductivity in a metal results from the metal atoms having?
Conductivity in a metal results from the metal atoms having loosely held electrons that are free to move and carry electric charge. These free electrons can easily flow through the metal lattice, allowing for the efficient transfer of electrical energy.
What Is the mobile Valence electrons in a metallic bond?
In a metallic bond, mobile valence electrons, often referred to as "sea of electrons," are the electrons in the outermost energy levels of metal atoms that are not tightly bound to any specific atom. These delocalized electrons can move freely throughout the metallic structure, allowing metals to conduct electricity and heat efficiently. This mobility also contributes to the malleability and ductility of metals, as the atomic cores can shift without breaking the metallic bond.
Explain what does the strength of a metallic bond depends upon?
Number of valence electrons-The greater the number of freely mobile valence electrons, the higher the charge of positive metal ion, the stronger the metallic bond. Size of metal atom or ion-The smaller the size of the metal ion, the closer the nuclei of metal cations are to the delocalized mobile electrons, the stronger the forces of attraction between the electrons and nuclei, the stronger the metallic bonds.
What do mobile electrons do in metals?
Well metallic Bonds are positive metal ions surrounded by mobile electrons, in the bond the mobile electrons easily slide past one another when subjected to pressure. As for ionic crysal, pressure pushes ions of like charges into contact. They repel and crystal breaks apart.
What nonmobile nuclei are surrounded by a sea of mobile electron?
Conduction Band
What bond is iron and iron?
It's the Metallic Bonding .The iron atoms form (+ve)ions that are surrounded by a sea of mobile (delocalised) free valence electrons.
Is a metals luster is due to its valence electrons?
Most of the properties of a metal, including lustre, are due to the metallic bonding of the electrons.
Why metals good electrical conductors?
In their regular (lattice) structure, metals have a sea of free electrons. This allows the electrons to flow through the metal at will and this is what makes metals good conductors of electricity (and heat).Their mobile electrons

The electric current in a metal conductor is carried by?
The electric current in a metal conductor is carried by the flow of electrons. Electrons are negatively charged particles that move in response to an electric field, allowing for the transfer of energy and the generation of electrical power.

How does the valence electrons make metals good conductors or hear and electricity?
Valence electrons in metals are delocalized, meaning they are free to move around the metal's structure. When a voltage is applied, these mobile electrons can flow easily, allowing metals to conduct electricity and heat efficiently. This ability is due to the metallic bonding, which involves the attraction between positive metal ions and the shared 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.
What do valence elctrons do?
They are typically the electrons which are involved in forming bonds to other atoms (as opposed to the other so-called "core" electrons which do not interact much with other atoms or molecules. (This is for WHAT they are not what they DO) (stupid answer by the way man)
What Cations bonded together by mobile electrons examples?
An example of cations bonded together by mobile electrons is metallic bonding. In metallic bonding, metal cations are surrounded by a "sea" of delocalized electrons that move freely throughout the structure, holding the cations together in a lattice. This is commonly seen in metals such as copper, iron, and aluminum.
How is pure metal held together?
Metals are held together by metallic bonds. Metallic bonds consist of the attraction of the free-floating valence electrons for the positively charged metal ions. These bonds are the forces of attraction that hold metals together. Metals are made up of closely packed cations rather than neutral atoms. The valence electrons of metal atoms can be modeled as a sea of electrons. The valence electrons are mobile and can drift freely from one part of the metal to another. Metallic bonds consist of the attraction of the free-floating valence electrons for the positively charged metal ions. These bonds are the forces of attraction that hold metals together.
