Chem U7

Electronegativity and Bond Type; Polarity

hybridization the blending of s and p orbitals
electronegativity atom's electron attracting ability; arbitrary scale w/4.0 being the highest
nonpolar covalent bond 2 atoms share electrons equally (same strength) (mix of - and +)
polar covalent bond electrons aren't shared equally btwn atoms (one is stronger than the other) (one side is + or -)
ED 0.0-0.4 bond? nonpolar covalent
ED 0.5-1.6 polar covalent
ED equal to or greater than 1.7 Ionic
which structures are always polar?l bent and pyramidal
when do lone pairs affect the shape of the atom? when it is on the central atom
dipole a molecule w/electrically charged poles; one side is + or -
