What is conduction band ?

Valanece bond overlaps with conduction band in case of metals ,True or False.

Explain the formation of energy bands in solids and hence define conduction band and valence band.

What do you mean by valence band, conduction band and forbidden gap?

The lowest unfilled energy band formed just above the valence band is called conduction band. (True/false)

Fill ups If there is a large energy gap between the filled valence band and empty conduction band, the subtance acts as …………….. .

Fill in the blanks: The conduction band of an insulator is ...........empty.(partially, fully).

Carbon, silicon and germanium have four valence electrons each. These are characterised by valence and conduction bands separated by energy band gap respectively equal to (Eg)_C , (Eg)_Si and (Eg)_ Ge . Which of the following statements is true?
