Chem U7
Electronegativity and Bond Type; Polarity
Question | Answer |
---|---|
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 - |
