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

Explanation:

The Bohr model proposed that electrons move in fixed, circular orbits around the nucleus. The first option is incorrect as it's not a single cloud layer. The third option is more related to quantum - mechanical models (electron cloud). The fourth option is wrong as electrons are in motion.

Answer:

All electrons move in a circular orbit around the nucleus.
