Electron Configuration

• Rachael Dorr
• Period 6

2
What is it?

• The arrangment of electrons among the various
  orbitals of an atom.

3
Quantum Numbers

• N energy level
• L sub level
• M- specific orbital
• S spin

4
Rules to know

• Pauli exclusion principle
• in order to occupy the same orbital, electrons
  must have opposite spins.
• Honds rule
• Seats on the bus (spread out).
• Heinsburg uncertainty principle
• Impossible to know the exact location/velocity of
  an electron.
