1. Noble Gas Configuration

2. Warm up: Electron Configuration Review
Element
E-Configuration
Hydrogen
Beryllium
Phosphorous
Arsenic
Rubidium
Cadmium
Platinum
Barium

3. Now that you have mastered electron Configuration…..
There is a short cut NOBLE GAS NOTATION Xe He Rn Kr Ar

4. Where do we find the Noble Gasses on the periodic Table?

5. How does it work?
Determine the noble gas that comes just BEFORE the element in which you are trying to complete it’s electron configuration
Put that noble gas’s symbol in brackets to start the configuration
Start the configuration from there, not from the beginning

6. Oh! That’s much easier! I like that much better!
try this:
Iodine:
Long format: 1s22s22p63s23p64s23d104p65s24d105p5
Noble Gas Format: [Kr] 5s24d105p5
Oh! That’s much easier! I like that much better!

7. Why use Noble Gas Configuration?
It makes writing electron configurations and orbital notations much shorter and easier
It makes writing electron configurations and orbital notations much shorter and easier.

8. Practice: Element Noble Gas Configuration Magnesium Sulfur Cobalt
