C) Limitations of Bohr Model
1) electron couldn’t circle around nucleus like a planet! …
Because they would lose energy (by emitting electromagnetic radiation) & spiral into nucleus.
2) Bohr was not able to explain electron orbits of large atom w/ many electrons

When you are studying sub-atomic particles, you change them.
(A particles position and momentum are affected by your measuring devices.)
The more you know
Electrons do not have precisely described positions and momenta
The 'probable' position and momenta are described mathematically
Electrons occupy regions in space called 'clouds'.
