According to Octet-rule atoms are stable when there are eight electrons in their valence shell. ... This excess electron is free to move and is responsible for conduction. Hence N-type (Negative Type) extrinsic semiconductor (silicon in this case) is made by doping the semiconductor with pentavalent element.
