and both have the same lattice structure, having bonding electrons in each. However, is an insulator whereas is an intrinsic semiconductor. This is because:
1. in the case of the valence band is not completely filled at absolute zero temperature.
2. in the case of the conduction band is partly filled even at absolute zero temperature.
3. the four bonding electrons in the case of lie in the second orbit, whereas in the case of they lie in the third.
4. the four bonding electrons in the case of lie in the third orbit, whereas for they lie in the fourth orbit.

Preparing Energy Band Theory for NEET

Energy Band Theory is a specific sub-topic that frequently appears in the NEET examination. Understanding the underlying principles and practicing targeted questions is key to mastering this concept.

The questions compiled above are previous year questions (PYQs) directly related to Energy Band Theory. Practicing these specific questions helps you understand the difficulty level and the examiner's approach to this topic.

Topic Frequently Asked Questions

Is Energy Band Theory a high-weightage topic?

You can refer to the priority and consistency badges at the top of this page. High priority topics should be thoroughly revised multiple times before the exam.

Should I memorize the solutions?

No, it is highly recommended to understand the core concept and methodology behind each solution rather than memorizing them, as exact questions are rarely repeated, but the concepts definitely are.
