Question

The metallic luster exhibited by sodium is explained by

Diffusion of sodium ions
Oscillations of loose electrons
Excitation of free proton
Existence of body centered cubic lattice

Answer 1

Heya,

The metallic luster exhibited by sodium is explained by Oscillations of loose electrons.

So, the option (2) Oscillations of loose electrons is correct answer.

Hope this helps....:)

Answer 2

The factor which accounts for metallic luster of sodium is oscillation of loose electrons.

Explanation:

• The availability of loose electrons acts as the major reason for the lustrous appearance of metals.
• Sodium being a metal also exhibit this property.
• At the point when light falls upon the loose or free electrons, they assimilate energy and are set into motions, and they produce radiations.
• So the metallic shine showed by sodium is clarified by wavering of free electrons. Henceforth choice B is right.
