Nobel Gas Configuration w/some Lewis Dot

​Noble Gas Configuration

1. A shorthand way of writing the configuration by using the last noble gas before the element. 

2. Then, write the symbol of the noble gas in brackets. 

3. Finally, write the remaining configuration after the brackets.

• Ex: Fluorine:   [He] 2s2  2p5

Examples:

​Bromine:

Argon:
