Chem 11 – Class Starter. Please take out your Periodic Table “cut-ups ” and place them on your table If this makes more sense, why are periodic tables laid out the way they are ? Practicality…. Soon… this “alternative” model of the Periodic Table will become very important to us….

If this makes more sense, why are periodic tables laid out the way they are?
Collect the Quantum Revolution Worksheet from the front of the room
In about 8 minutes we will review as a class
One electron system
BOTH ARE BOTH!?!
It took several years, several scientists, and some outside the box thinking to develop the current model of the atom…
Population Density of BC
If you had to make a bet (non monetary of course) on finding a specific person, when you have no prior knowledge of where they live, where in BC would you choose?
The electron is a particle that must be in orbital in the atom.
The electron is like a cloud of negative energy or a wave.
Orbitals are areas in 3D space where the electrons most probably are.
The energy of the electron is in its vibrational nodes- like notes on a guitar string.
Photons are produced when high energy nodes change to lower energy nodes
We now have subshells within shells…
Oh and by the way… even though they are called shells they are ACTUALLY probability densities
n = 7
n = 6
n = 5
n = 4
n = 3
