Answer:
gallium
Explanation:
Gallium is the element that would be best suited as a dopant for p-type semi-conductor because it belongs to the third group on the periodic table.
Elements with 3 valence electrons are best used as dopant for p-type semi-conductors.
- A dopant is a material used to produce a broad range of characteristics in semi-conductors.
- Semi-conductors allows heat and electricity to pass through under some certain conditions.
- In n-type semi-conductors elements with 5 valence electrons are best used.
- Gallium is the only element in this choice that have 3 valence electrons and this will favor its usage as a dopant in a p-type semi-conductor.
