Question

conduction of electricity in metallic bonding is due to presence of​

Answer 1

Answer:

metal contain free moving delocalized electrons . when electric voltage is applied , an electric field within a matal triggers the movement of the electrons making them shift from one end to another end of the conductor.

Answer 2

The presence of mobile electrons causes the electrical conductivity of a metal.

• When a potential difference is applied across a metal, the free mobile electrons in the metallic crystal move toward the positive electrode.

• The electrons can move freely within molecular orbitals, and so each electron becomes detached from its parent atom.
• Metallic bonding is the electromagnetic interaction between loosely held, delocalized, valence electrons, gathered in an "electron sea", and the metallic nuclei within metals.
• This type of bonding is seen as the sharing of "free" electrons among a lattice of positively charged ions (cations).
• The electrons are said to be 'delocalized'. The metal is held together by the strong forces of attraction between the positive nuclei and the delocalized electrons.
• This is sometimes described as "an array of positive ions in a sea of electrons".
