CHEM H90 Lecture Notes - Lecture 14: Covalent Bond, Ionic Bonding, Nonmetal
Document Summary
N and it turns out that the number for cl is a tiny bit bigger than for n. In actual fact, there are about 6 different tables of electronegativities: a slightly fuzzy concept. In reality, it doesn"t (cid:373)atte(cid:396) (cid:271)e(cid:272)ause (cid:449)he(cid:374) t(cid:449)o ele(cid:272)t(cid:396)o(cid:374)egati(cid:448)ities a(cid:396)e that (cid:272)lose, you (cid:272)a(cid:374)"t de(cid:272)ide (cid:449)hi(cid:272)h is (cid:449)hi(cid:272)h: for convention purposes, stick with this. Week 3: quantum versus classical view, electronic configurations, order of energy levels, letters of different shaped orbitals, absorb photon atom is excited, atom de-excites emits photon, how periodic table gets shape. Week 4: bonding: distinguish strong bonds (covalent, ionic, metallic) from weak (hydrogen, van der waals) Ionic bond: electrons transferred, between metal and non-metal, name: metal non-metal(ide, large electronegativity difference, usually solids that are poor conductors. Week 5: organic chemistry has c in it, studied almost only hydrocarbons, named by longest c chain, know condensed structural formula, know line structures.
