Principles and Rules
Heisenbergs Uncertainty
Principle
It is impossible to know the location and velocity of an electron
at the same time
Hund's Rule
Electrons spit Opposite in Orbital
Paul's Exclusion Principle
1 or 2 Electron per Orbital
Aufbau Principle
Electrons occupy the lowest energy level first
Bucket filling with Water
bottom to top
Model of the Electron
Plum Pudding
Electrons stuck in a sphere
Orbital Model
Electrons "orbit" the Nucleus in specific
paths like the planets that orbit the Sun.
Today's Model
Quantum Mechanical Level
Atomic Orbitals
Principal Energy Levels
n=1
1 sublevel
n=2
2 sublevel
n=3
n=4
Tells how likely it is to find an electron in various
locations around the Nucleus
Maximum Electrons for each Level
