Physical Science Electron Dot Diagram

Valence Electrons

Are outer Electrons

Filled energy levels

Atoms a stable configuration like that of the nearest noble gas

Electron Dot Diagram

Can be used for single atoms, or to represent how electrons rearrange during chemical BONDING

Ionic Bonds

Cations lose valence electrons to become POSITIVELY charged, METALs, ANIONS gain valence electroncs and become negatively charged NONMETALS

Covalent Bonds

Molecular bond, atoms SHARE valence electrons to follow the octet rule.

Outer Electrons

Most important because they participate in BONDING.

octet rule

States that atoms lose, gain or share valence electrons to have filled energy levels. (8)

Lewis Dot/Electron Dot Diagram

show an atom's valence electrons as dots drawn around it's chemical symbol.

Covalent Bonds are represented
