|
Battery Capacity
|
the amount of electrons (the total charge) it can deliver
|
|
|
Oxidation is and occurs in
|
loses an electron; anode
|
|
|
Reduction is and occurs in
|
gains an electron; cathode
|
|
|
Metal to Metal Reaction
|
Metallic Bonding
|
|
|
Non-Metal to Non-Metal Reaction
|
Covalent bonding
|
|
|
Non metal to metal reaction
|
ionic compound
|
|
|
Covalent bonding
|
electron sharing
|
|
|
Ionic Bonding
|
Electron transfer
|
|
|
Metallic bonding
|
electron sharing
|
|
|
electronegativity
|
the tendency of an atom to attract electrons to itslef
|
|
|
metal atoms
|
excess electrons; poor electronegativity
|
|
|
non metal atoms
|
lack electrons; high electronegativity
|
|
|
electronegativity on the periodic table
|
increases from left to right, decreases from up to down
|
|
|
shielding
|
tendency of inner shell electrons to diminish the attraction of outer valence electrons to nucleus; shielding weakens electronegativity
|
|
|
Solid Ionics
|
high melting, hard, brittle, crystalline, non-conductive of electricity
|
|
|
Oxidation Reduction Reactions (Redox)
|
Reactions involving electron transfer
|
|
|
Voltaic Cell
|
produces a positive voltage; electrons flow from anode to cathode; ions complete circuit thru salt bridge
|
|
|
Electrolytic reaction
|
negative voltage; non spontaneous; foreced to run using external power source
|
|
|
electrolysis
|
used for two purposes: 1) recharging voltaic cells (batteries) 2) producing materials (including electroplating)
|
|
|
Buckyballs
|
ultimate nano-ball bearing; conductive particles; can trap an atom inside; no real uses yet
|
