A solid reflects incident light and its electrical conductivity decreases with temperature. The binding in this solid is
Options:
Answer:
C
Solution:
Metals reflect incident light by the vibrations of free electrons under the influence of electric field of incident wave. The conductivity of metals decreases with increase of temperature due to increases in random motion of free electrons. The bonding is therefore metallic.
