All the valence electrons present in a crystal of silicon are bounded in their orbits by:
Correct answer: A. Covalent bond
- A. Covalent bond
- B. Ionic bond
- C. Molecular bond
- D. None of these
Explanation
As silicon is a non metal all of its valence electrons will form covalent bonds by sharing if electrons to fill their outermost shells and gain stability.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
