Based on equation E = –2.178 \times 10–18J, Z2n2 certain conclusions are written. Which of them is not correct?

1. Larger the value of n, the larger the orbit radius.
2. Equation can be used to calculate the change in energy when the electron changes orbit.
3. For n = 1, the electron has a more negative energy than it does for n = 6 which means that the electron is more loosely bound in the smallest allowed orbit.
4. The negative sign in the equation simply means that the energy of the electron bound to the nucleus is lower than what it would be if the electrons were at an infinite distance from the nucleus.

Preparing Bohrs Theory for NEET

Bohrs 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 Bohrs Theory. Practicing these specific questions helps you understand the difficulty level and the examiner's approach to this topic.

Topic Frequently Asked Questions

Is Bohrs 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.
