The Bohr Model is an early 20th century model of the atom that was developed by Danish physicist Niels Bohr. It is based on the idea that electrons orbit the nucleus in discrete orbits, with each orbit having a specific energy. In the Bohr Model, the electrons can only exist in certain orbits and must “jump” from one orbit to another when they gain or lose energy. While this model was eventually replaced by the quantum mechanical model, it can still be helpful in understanding the structure of atoms.

So which statement below doesn’t follow the Bohr Model?

• A) An electron can occupy any energy level.
• B) Electrons can only exist in certain orbits.
• C) Electrons can move freely between orbits.
• D) Electrons must absorb or emit energy to move between orbits.

The correct answer is A. In the Bohr Model, electrons can only occupy certain energy levels and cannot exist in any arbitrary energy level. This means that they can only exist in certain orbits that are spaced at set distances from the nucleus. Electrons must also jump from one energy level to another by absorbing or emitting energy in order to move between orbits.

The Bohr Model is a relatively simple way of understanding the structure of an atom, but it is far from perfect. While it does provide a useful foundation for understanding electrons and their behavior, it should not be relied upon as an accurate or complete description of modern atomic theory.
