Resource summary
Chemistry of Life
Intro to Biochemistry
basic structure of atom
atomic number = # protons
also # electrons when overall charge neutral
atomic mass = # protons + neutrons
matter - "stuff"
element - pure substances of earth
ex. C, Al, O, N
atom - single unit of element
ex. H+ is atom
compound - combination of elements
ex. H2O
molecule - 2 or more atoms combined
ex. O2, FeSCN
bonds
covalent - share electrons
polar covalent
one electronegative element + less electronegative element
gives more e- element slightly negative charge
gives less e- element slightly positive charge
ex. O-H, C-O
nonpolar covalent
equal distribution of electrons
ex. C-C, C-H
single - one pair e-s
double - two pair e-s
triple - three pair e-s
ex. C-=C
ex. O=O
ex. H-H
reactions
endergonic - PEi < PEf
PEi > PEf
