Q. Metallic lusture is explained by
A) Diffusion of metal ions
B) Oscillation of loose electrons
C) Excitation of free protons
D) Existence of bcc lattice
Explanation
(b)
The metals have low ionization energy. In a piece of metal many free electrons are found which move form one atom to other. The presence of mobile electrons or oscillation of loose electrons are responsible for metallic lusture.
