What did Niels Bohr discover about electrons?
Electrons orbit the nucleus in fixed energy levels
Protons circle the nucleus in fixed energy levels
The nucleus circle the atom
Electrons don't exist
The Heisenberg Uncertainty Principle tells us that we cannot know what at the same time?
Mass and charge of an electron
Number of protons and neutrons
Location, size, and momentum (includes speed) of the nucleus
position and momentum (includes speed) of an electron
Who discovered the nucleus?
Rutherford

What's the difference between these two atomic models?
The Bohr model has specific paths for the electrons, whereas the Rutherford model just has electrons wherever
The Bohr model has a nucleus and the Rutherford model doesn't
The Rutherford model has electrons because Rutherford discovered the electron
Rutherford's model is slightly smaller because Bohr felt like he deserved it

An atom consists of a nucleus and a cloud of electrons.
Atoms cannot be subdivided, created, or destroyed.
In chemical reactions, atoms are combined, separated, or rearranged.
