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