What is the difference between the Electron Cloud Model and the Bohr Model

• placement of the electrons
• placement of the neutrons
• placement of protons
• Bohr model did not include a nucleus

In the Planetary Model of the atom, Niels Bohr stated that the electrons were located in:

• the nucleus

• pulsars

• energy shells

• the atom

Created a model of the atom with electrons moving around the nucleus in fixed orbits

• Bohr
• Dalton
• Heisenberg
• J J thomson

Bohr's model of the atom proposed that ___.

• electrons move around the nucleus in fixed orbits
• neutrons move around the nucleus
• neutrons do not exist, but are just paired protons and electrons
• the nucleus spins
