2. has fixed space around the nucleus.

3. is stationary in various energy levels.

4. moves around the nucleus in definite energy levels.

Q.

Electrons in an atom revolve around the nucleus in certain selected concentric paths which are called orbits. Which of the following orbit do you think will have highest energy?
