Semiconductor Principles

Q1:

Elements with 1, 2, or 3 valence electrons usually make excellent:

A conductors

B semiconductors

C insulators

D neutral

ANS:A - conductors

When (1, 2, 3) outer valance electronics less no. So there is a chance to more availability of another atom electrons makes free and max conductivity exist.

Outermost orbit electronics increases conductivity effect impact by another atom decreases.
