Read each question carefully and answer to the best of your ability. Refer to the Bohr model diagram provided where necessary.
Observe the diagram of a Bohr model atom below:
1. In the Bohr model, electrons orbit the nucleus in specific paths called:
Clouds
Energy levels
Random orbits
Nuclei
2. According to the Bohr model, what happens when an electron moves from a higher energy level to a lower energy level?
It absorbs energy.
It emits energy.
Its mass increases.
Its charge changes.
3. The central part of an atom, containing protons and neutrons, is called the .
4. Electrons in the outermost shell are known as electrons.
5. The Bohr model accurately describes the exact path of electrons around the nucleus.
True
False
6. Each energy level in the Bohr model can hold an unlimited number of electrons.
True
False
7. Briefly describe the main contribution of Niels Bohr to our understanding of atomic structure.
8. Explain why electrons in the Bohr model occupy specific energy levels instead of continuously losing energy and spiraling into the nucleus.
