An atom with 5 electrons in its outer shell is part of
- a C type material.
- a P type material.
- an N type material.
Explanation
A pentavalent atom with five outer-shell (valence) electrons acts as a donor: four electrons bond into the lattice and the fifth is free to conduct, creating an excess of negative carriers. This produces N-type material. Trivalent (three-electron) dopants instead create P-type.
