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

Silicon has 4 outer most valence electrons.

What is semiconductor atom?
Girish said:

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

Yes it is true that semiconductor have 4 electrons in outer most shell and conductor have less than 4 electron in the outer most shell and insulater have 8 electron in outer most shell.

@Girish.
Please tell me more about semiconductors.
Please tell me more about semiconductors.

Semi conductors are the devices whose conductivity lies in between the insulators and pure conductors. In general some elements from 3A (BORAN) , 4A (Si, Ge) , 5A (As, Sb) 6A (Te, Po) are the semiconductor metals having unfilled valency electrons.

@ nitin
When no of valence electron in an atom is less than 4 , the material is usually a metal and a conductor. ex:sodium, magnesium, alluminium which have 1, 2 , 3 valence electron respectively.
When no of valence electron in an atom is more than 4 , the material is usually a non metal and a insulator.Ex:nitrogen, sulphur, neon which have 5, 6 ,8 valence electron respectively.
