explain electrical conductivity of metals and non metals
Answers
Electrical Conductivity in Metals. Electrical conductivity in metals is a result of the movement of electrically charged particles. The atoms of metal elements are characterized by the presence of valence electrons - electrons in the outer shell of an atom that are free to move about.
Hope it help u.....
Answer:Metal conduct electricity in solid as well as molten state .the conductivity of metal depend upon the number of valence electron available per atom .the atomic orbital of metal atoms are so close in energy who formed a band if this band is partially filled or overlapping band than electron can flow easily under and applied electric field and metal shows conductivity.

.
for non metal if the gap between valence band is large then electron cannot jump to it and such a substance has very small conductivity and it behave as an insulator
