what did the bohr model assume about the motion of electrons?
electrons do not have a specific path around the nucleus.
all electrons move in a single cloud layer around the nucleus
electrons always remain in the same location around a nucleus
all electrons move in a circular orbit around the nucleus

Explanation:

The Bohr model proposed that electrons move in circular orbits around the nucleus. It was a significant step in understanding atomic structure. The other options are incorrect:

• Electrons do not have a specific path (as per quantum mechanics, not Bohr's model).
• Electrons are not in a single cloud layer (this is more related to electron - cloud models).
• Electrons are not stationary (they are in motion around the nucleus).

Answer:

All electrons move in a circular orbit around the nucleus.
