Document Summary

1. polar molecule: unequal sharing of electrons (if one of the nucleus is more positively charged then it will attract electrons a little bit more), atom becomes more electronegative and this leads to an asymmetric distribution. 2. non-polar molecule: equal sharing of electrons, atoms are of similar size, so they share the electrons equally (ex. molecule that consists of c & h), they are not soluble in water because they are not polar, hydrocarbons. 3. ionized molecule: when an atom is so electronegative that it can capture electrons from another ataom (gains becomes anion, and loses becomes cation) Non-covalent bonds (govern interaction between molecules or different parts of a larger biological molecule (typically weaker)): 4. ionic bond: atoms or molecules with pos or neg charges that attract each other (dna is very negative, dna binding proteins are very positive and both will bind together)
