Chemistry Chapter 7 Section 1

Neils Bohr developed a famous model of atoms with electrons in orbit around the nucleus.

Neils Bohr worked on the splitting of atoms.

Neils Bohr was once living in Nazi Germany.

Neils Bohr left France during the French Revolution.

Neils Bohr worked on the Manhattan Project that invented the atom bomb.

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.

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

The Heisenberg uncertainty principle says that you can not measure both the velocity and position of an electron at the same time.

•The Heisenberg uncertainty principle lead to the development of the electron cloud model.
