Valence shell is the outer most shell and has least of 4 electrons for conductors.

If it has 8 valance electron it is completely filled.
Since semiconductor is partially filled its valance electron is 4.
Since semiconductor is partially filled its valance electron is 4.

More the no. of valence electrons then more the strength of bond will be. Thats why noble gases(with 8 valence e they are inert to react).
We classify substances which ve
1,2,3 valance e - conductors
exactly 4 valance e - semi conductors
5,6,7 valance e - insulators
8 valance e - noble gases

Semiconductors are insulators. When we add impurities or increase the temperature, it will become conductor. Thats why it s semiconductor.

Hey guys, please tell me what is mean of valence electrons ?

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

Atomic number of silicon=14
Atomic number of Germanium=32
Electonic Structure of si=2,8,4
Electonic Structure of Ge=2,8,18,4
so valence electron of semi conductors are 4(four)

Semiconductors are devices whic properties lies between conductor and insulator.
