gilbert n lewis |
american chemist who discovered first successful theory of chemical bonding |
|
|
what was lewis's theory |
usual stability of group is 8A elements or noble family |
|
|
stability |
full valence shell of electrons |
|
|
octet rule |
8 valence e- |
|
|
how do you get the lewis structure from 20Ca |
look for the highest mnemonic (4 in given example) and the orbital (2) so put two dots in Ca |
|
|
I,II,III A |
loose electrons |
|
|
V,VI,VII A |
gains electrons |
|
|
exceptions to the octet rule 01 molecules with an odd number of electrons |
free radicals (covalent, nitrogen + oxygen) |
|
|
exceptions to the octet rule 02 less than octet |
electron deficient (ionic, boron + chlorine) |
|
|
exceptions to the octet rule 03 more than an octet |
hypervalent molecule (covalent, phosphorus + chlorine) |
