Electronegativity attracts/wants a lot of electrons (ex. h20; O2's electronegativity leads to an unequal sharing of electrons between hydrogen and oxygen; aka it's a polar molecule) Hydrogen Bonds Very weak, but if you have enough of them. they can be significant (ex. a lot of water molecules can lead up to surface tension) Ionic Bonds When electrons from 1 atom are TRANSFERRED to another (ex. NaCl, Na loses an e-, now it is positively charged, and Cl accepts the e-, so it becomes neg. charg...
