Question

In metallic bonding the electricity conduction is due to the presence of :

• A. lattice
• B. nucleus
• C. protons
• D. delocalized electrons

Answer 1

The correct option is D delocalized electrons

The electrons can move freely within molecular orbitals, and so each electron becomes detached from its parent atom. The electrons are said to be delocalised. The metal is held together by the strong forces of attraction between the positive nuclei and the delocalised electrons.This is sometimes described as "an array of positive ions in a sea of electrons".
