(a)
Interpretation:
Whether the given combination of elements would produce a semiconductor or not has to be explained
Concept Introduction:
Semiconductors are substances that conduct electricity either by addition of an impurity or by the effects of temperature on it. Semiconductors electrically conductivity lie between conductor and insulator. Semiconductors have small energy gap between valence band and conduction band.
The only elemental form of semiconductors is germanium, silicon and carbon (graphite form) whereas other semiconductors will have combination of elements whose valence electron count will total up to eight.
