In a metallic bond the nucleus of one atom is attracted by a near by atom's what?
In a metallic bond, the nucleus of one atom is attracted by the delocalized electrons in the electron sea formed by all the atoms in the metallic structure. This attraction allows the atoms to come together and form a stable structure held together by the strong electrostatic forces between the positive nuclei and the negative electrons.
What are Electrons floating in a sea of positive charge?
Orbits or orbitals
What is the difference between covalent bonds and metallic bonds?
In a covalent bond, the electrons can be defined by the atoms they are shared between; specific atoms are bound to specific others. In metallic bonding, the nuclei "float" in a sea of electrons. the electrons here are shared by the mass as a whole, with no nuclei being bound to any specific other nuclei and no electrons bound to any particular atoms.
What is the combination of free electrons and atomic nuclei called?
It is called recombinations of electrons and holes due to the oposite polarity of the charges.this proces is known to be 'diffusion'. It is called recombinations of electrons and holes due to the oposite polarity of the charges.this proces is known to be 'diffusion'.

What do delocalised valence electrons moving between nuclei do?
Delocalized valence electrons moving between nuclei become detached from their parent atom. The metal is held together by the strong forces of attraction between the delocalized electrons and positive nuclei.
What is a positive nuclei moving about in a sea of electrols referred to?
This probably refers to plasma. However the sea of electrons analogy is usually applied to metals. The metallic bond is present in the solid and in the melt. In the solid the nuclei are fixed in a lattice, when molten they move about.
What is the sea of electrons model?
The sea of electrons model is a concept in chemistry that describes the behavior of electrons in metallic bonds. In this model, metal atoms are considered as positive nuclei surrounded by a "sea" of mobile delocalized electrons. These electrons are free to move throughout the metal lattice, giving metals their characteristic properties such as high electrical conductivity and malleability.
What type of bond is formed when many atomic nuclei and core electrons of an element form a core and the valence electrons from all the atoms are free to move throughout the structure?
A metallic bond is formed in this scenario. It is characterized by a sea of delocalized electrons moving freely within the lattice of positive atomic cores, giving metals their unique properties such as electrical conductivity and malleability.
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 bond is formed when delocalized electrons are shared by all nuclei?
The bond formed when delocalized electrons are shared by all nuclei is called a metallic bond. In this type of bonding, electrons are not associated with any specific atom but are instead free to move throughout the metal lattice, creating a "sea of electrons." This delocalization contributes to the unique properties of metals, such as electrical conductivity and malleability.
In a metallic bond the nucleus of one atom is attracted by a near by atom's what?
In a metallic bond, the nucleus of one atom is attracted by the delocalized electrons in the electron sea formed by all the atoms in the metallic structure. This attraction allows the atoms to come together and form a stable structure held together by the strong electrostatic forces between the positive nuclei and the negative electrons.
Why does metalic bonding cause metals to conduct electric current?
Metallic bonding involves positive metal cations surrounded by a 'sea' of delocalised electrons. These delocalised electrons are able to move freely as they are not joined to one particular atom. Normally, these electrons are moving completely randomly and so their resultant velocity is zero. However, when a potential difference is applied, these electrons gain a small resultant drift velocity that enables them to flow as an electric current.

Orbits or orbitals
Why is the number of electrons more than nucleus in the sea of electrons model?
In any neutral object the number of electrons is equal to the number of protons. All metallic elements contain more than one proton in the nucleus. Therefore there will be more electrons than atomic nuclei.
