Models of electrons
Plum pudding- Thomson
Electrons stuck in a sphere
orbital model - Bohr
electrons orbit the nucleus in specific paths like the planets orbit the sun
Today's model: Electron cloud model
the principles and rules
Hund"s rule
electrons spin in opposite directions in a orbital
pauli's exclusion principle
1 or 2 electrons per orbital
Aufbau principle
electrons occupy the lowest energy level first
bucket filling with water from bottem to top
Heisenberg's Uncertainty Principle
it is impossiple to know the location and velocity of an electron at the same time.
