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.
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.
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.
The electrons that form bonds are called valence electrons. These electrons are in the outer most shell of an atom.

The number of valence electrons determines the strength of the metallic bond. The more the stronger the bond will be.
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.
It's the Metallic Bonding .The iron atoms form (+ve)ions that are surrounded by a sea of mobile (delocalised) free valence electrons.
Metallic bond has the characteristic of a sea of mobile electrons, where electrons are delocalized and free to move throughout the structure. This mobility of electrons allows metals to conduct heat and electricity efficiently.

The three types of chemical bonds include the ionic bond, wherein bond is formed when one atom accepts or donates its valence electrons to another atom. Another chemical bond is the covalent bond, wherein bond is formed when atoms share valence electrons. Metallic bond is formed when electrons are shared by two metallic atoms.
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.

The electrons that form bonds are called valence electrons. These electrons are in the outer most shell of an atom.
A shared metallic bond is a type of chemical bond that occurs between metal atoms within a metallic crystal structure. In this bond, metal atoms share their valence electrons with neighboring atoms, forming a "sea of electrons" that allows for the high electrical conductivity and malleability characteristic of metals.
No, that is not an example of a covalent bond. In this case, the ions surrounded by valence electrons in a bar of pure iron are held together by metallic bonding, where the valence electrons are free to move throughout the structure. Covalent bonds involve the sharing of electrons between atoms to form molecules.
