• Neils Bohr worked on the splitting of atoms.

• Neils Bohr was once living in Nazi Germany.

Multiple Choice

What was on the previous slide?

• a periodic table

• a configuration map

• an aufbau diagram

• a polyatomic chart

Multiple Choice

Which is correct?

• The interpretation of the places with closely spaced lines in an emission spectrum is that the electrons are jumping between different energy levels.

• The interpretation of closely spaced lines in emission spectrums is that they are very close in energy which suggests the existence of sublevels within energy levels.

Multiple Choice

Which is not true?

• •The Heisenberg uncertainty principle says that you can not know the location of an electron without knowing its velocity.
