AP EAMCET · Chemistry · p Block Elements (Group 13 & 14)
Which of the following statements are not correct?
(A) Diode is a combination of \(n\)-type and p-type semiconductors.
(B) Silicon or germanium is electron rich impurity.
(C) Phosphorus and arsenic are electron deficient impurities.
(D) Schottky defect decreases the density of the crystal.
- A B, C
- B A, D
- C C, D
- D A, C
Answer & Solution
Correct Answer
(A) B, C
Step-by-step Solution
Detailed explanation
Among the given statements, (B) and (C) are incorrect. Their correct explanations are as follows: (B) Silicon or germanium belong to group 14, so they can be used as semiconductors. (C) Phosphorus and arsenic belong to group 15, so they have 5 valence electrons. Out of 5…
