Question
The energy gap between the conduction band and the valence band is large for
Question 38 options:
superconductors.
A metal such as chromium in the face-centered cubic lattice will have ________________ atom(s) per unit cell.
Question 34 options:
1) conductors. 2) insulators. 3) semiconductors. 4) alloys. 5)superconductors.
Explanation / Answer
Solution :-
1) The energy gap between the conduction band and the valence band is large for Insulators
The insulators is the material in which the eneergy gap is is very large therefore it do not transfer electricity or heat.
2) A metal such as chromium in the face-centered cubic lattice will have ________________ atom(s) per unit cell
Answer = 4
because [( 18 × 8 from the corners) + (12 × 6 from the faces)] = 4
