Answers| Latest Update
Shot atoms at a gold plate and most went through but a few bounced back showing that most
of the atom was space, but there was a dense nucleus that sometimes came in contact with the
gold plate.
Photon Bundle of Light energy
How do Atoms emit Light? Energy is given to an electron and it jumps to an outer shell.
When the electron returns home to its original shell, it releases the energy and emits light.
Why is the color emitted specific to the element? Because they are quantized and have a
different number of electrons
Quantized The energy is specific to each electron
Bohr's Model Predicts that electrons move in a circular pattern. This model only worked
for Hydrogen and does not work for any other elements because electrons do not normally
move in a circular pattern.
Wave Mechanical Model The way electrons move and how they account for the electron
cloud.
Quantum Numbers The purpose of quantum numbers is to find the general area of
electrons.
Pauli Exclusion Principle 1. Principle - Indicates the most probable distance of electrons
form the nucleus
2. Orbital - Electron cloud shape/ location of electrons within the energy level
