Electron Configuration
Examples of electron configurations
Valence Electrons
electrons on the the outer most shell
Bohr Diagram
This is a diagram of the electrons in a element
Lewis Structure
this is a diagram where the dots represent valence electrons
octet rule
The octet rule is a chemical rule of thumb that reflects observation that atoms of main-group elements tend to combine in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas.
