A) an insulator
B) a conductor
C) a semiconductor
D) a supersonic conductor
Correct Answer: B
Solution :
In magnesium, 3s energy band is completely filled. The filled 3s- energy band overlaps an empty 3p- energy band. Due to this, electrons flow under applied electric field from occupied band to unoccupied band. Thats why Mg is a conductor.You need to login to perform this action.
