Noble Gas Configuration

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

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

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

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

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!

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.
