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
with DASHES instead of dots in the dot diagram
