When the no.of valence electron is less than 4 then that will be a metal ion and when the no.of valence electron is more than 4 then it is a nonmetal.
But if the no.of valence electron is exactly 4 then it is a semiconductor.

The outermost orbit of an atom is called as valence shell.
The number of valence electrons present in a valence shell is based on its capacity.
For example: take silicon a semiconductor, which has 4 valance electrons.

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

Eletron structure of si= 2,8,4.
Eletron structure of ge=2,8,18,4.
Eletron structure of ge=2,8,18,4.

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.

Some semiconductor may be develop by taking element of 3A & 5A like GaAs.

The resistance of semiconductor lies between conductors and insulators and it is a negative temperature coefficient material i.e. when temperature increases the resistivity of the material decreases.

1,2,3 valance is - conductor.
4 is - semiconductor.
5,6,7 is - insulator.
8 valance is - noble gas .
So valence electrons are in semiconductor is 4.
4 is - semiconductor.
5,6,7 is - insulator.
8 valance is - noble gas .
So valence electrons are in semiconductor is 4.
