Hund's rule
Hund's rule
Electrons occupy separate orbitals before pairing
Valence electrons
Valence electrons
Outermost level electrons; determine chemical properties
Core electrons
Core electrons
Inner level electrons, exclude outermost
Cation formation
Cation formation
Atoms lose electrons from outermost level
