A semiconductor has a gap of 1 electron volt because of this valance band and conduction band can not overlap each each other. Thus flow of current is only possible when it get heated then valance band and conductor band overlap each other for example silicon and germanium which is used in making special type of semiconductor or you can say industrial devices like fet ujt zener diode triac diac devices.

Best example is silicon, but how can we justify is is for silicon from question?

A semiconductor remains partially full valence band and partially full conduction band at the room temperature.

Its temperature co-efficient is -ve. While conductors are +ve co-efficient of temperature.

OK for valence electrons are in the semi conductor.

The outermost orbit of the atom are valence orbit.
For semiconductor 4 valence electrons are there.
For semiconductor 4 valence electrons are there.

3 electrons in valency shell is worst, 4 better 5 bit better 6 best

Valence electrons are the electrons of an atom that can participate in the formation of chemical bonds with other atoms.
