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

We can also say using the bonds.
Conductor - Ionic bonds.
Insulator - covalent bonds.
Semiconductor - coordinate covalent bonds.

Semiconductor are those atom which are not conductor of electricity or not insulator i.e. its electricity lies b/w of them.

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.

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

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

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

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

@ manish bagga.. clerify whether conductors or insulators have more valence electrons...??

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