Are mobile electrons in the metallic bond responsible for luster?
it gives it its shine
What bond has the characteristic of a sea of mobile electrons?
Metallic bonds have the characteristics of a sea of mobile electrons.
Which type of bond forms a structure which is often described as an electron sea?
Metallic crystal consists of an assemblage of positive ions immersed in a sea of mobile electrons. Thus, each electron belongs to a number of positive ions and each positive ion belong to a number of electrons. The force that binds a metal ion to a number of electrons within its sphere of influence is known as metallic bond. This force of attraction is strong and is thus responsible for a compact solid structure of metals
Can a bond be a covalent and ionic bond?
No. A bond cannot be both covalent and ionic. A bond can be covalent, ionic or metallic. In covalent bonding electrons are shared, electrons are transferred in ionic bonding and electrons move about in a sea of electrons in metallic bonds.
What are the mobile electrons surrounding the positive ions called in a metallic bond?
This depends on where you are taught- some call it a sea of electrons some a cloud some delocalised elctrons.

Metallic bonds have the characteristics of a sea of mobile electrons.
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 is the the basis of metallic bond?
the attraction of metal ions to mobile electrons
Why is the metallic bond in aluminum stronger than metallic bond in sodium?
because the atoms are larger and cannot be held together as strongly by the mobile electrons.
What is a bond formed by the attraction between positively charged metal ions and the electrons around them?
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.
Can a bond be a covalent and ionic bond?
No. A bond cannot be both covalent and ionic. A bond can be covalent, ionic or metallic. In covalent bonding electrons are shared, electrons are transferred in ionic bonding and electrons move about in a sea of electrons in metallic bonds.
What determins the strength of metallic bond?
The number of valence electrons determines the strength of the metallic bond. The more the stronger the bond will be.

Which bond involves metallic ions surrounded by a sea of electrons?
Metallic bonds.
